multimds: fuse_default_permissions = 0 for kernel build test
liewegas pushed a commit that referenced this pull request Dec 14, 2016
Ported from Zheng's #22: 2e283ce

"This can reduce the test time becuase it avoids sending getattr request
whenever the kernel checks inode permission."

This is part of an effort to eliminate unnecessary differences between
multimds and fs suites.

# This is the 1st commit message:

DO-NOT-MERGE; first commit for integration of s3-select engine into RGW; the request can only sent by AWS client ; can execute on CSV files

# This is the commit message #2:

remove debug info

# This is the commit message #3:

bug fix (aggregation) ; error handling

# This is the commit message #4:

fix comments(to be continue);

# This is the commit message #5:

placement-new allocator;cosmetics

# This is the commit message #6:

add namespace ; memory-mng: response buffer is now class-member

# This is the commit message #7:

std::list --> std::vector

# This is the commit message #8:

replace boost::split with simple C csv parser; there is a big difference ; mainly because of too many allocation & copy

# This is the commit message #9:

performance improvement; upon star-operation using reusable-buffer to reduce copies and allocations

# This is the commit message #10:

performance improvement; reduce allocations and copies; using reusable buffer(std::string) for message meta-data also

# This is the commit message #11:

replace crc implementation with boost implementation; it also improve performance;

# This is the commit message #12:

performance improvement ; reduce the number of object value construction on intensive flow ( eval() );

# This is the commit message #13:

move from char* to std::string_view; change to csv_object interfaces mainly for performance improvements

# This is the commit message #14:

initial commit for column-alias supoort; next steps are error-handling(semantic, cyclic reference) and related performance improvements

# This is the commit message #15:

adding cache to column-alias, upon refer to alias more than once, it return cache result instead of executing the referenced-sub-tree; it can improve performance significantly (alias vs non-alias)

# This is the commit message #16:

cosmitcs; aggregation semantic validation is done just after syntax phase; error-messages for failed queries;

# This is the commit message #17:

adding validation for cyclic-alias-reference (endless evaluate-loop) ; its done by validating the call-stack-deph not crossing a threshold

# This is the commit message #18:

1) seperate headers for the s3-select-functions framework; 2)bug fix for copy-constructor

# This is the commit message #19:

adding new basic-type timestamp (boost::posix_time); adding to_timestamp,add_date,diff_date,extract_date functions;

# This is the commit message #20:

adding yuvalif utcnow (return current time) implementation

# This is the commit message #21:

adding CSV parser integrated with AWS-cli, the upgraded parser is able handle null columns, dynamic column/row/escape/quote char definitions. the CSV-parser is implemented with BOOST state machine.

# This is the commit message #22:

fix comments

# This is the commit message #23:

add escape rules ; default row-delimiter

# This is the commit message #24:

*) bug fix. in case of syntax error, send error-description back to client.
*) upon amount of runtime-error is crossing 100, abort query execution with error-message.
*) compression-type value is check for "NONE"

# This is the commit message #25:

adding initial s3-select documentation

# This is the commit message #26:

*)identation

*)add table for CSV behavior

*)add alias feature decription

# This is the commit message #27:

add csv-header-info handling, use: get csv schema by first line. ignore: skip the first line.

# This is the commit message #28:

add csv-header-info feature description

# This is the commit message #29:

*) handling broken-CSV-rows is done on s3select-engine (CSV s3select reader) *) RGW is executing s3-select on io-vec instead of calling c_str (it might realloc)

# This is the commit message #30:

adding s3 select documentation(to be continue ...) , s3-select is part of radosgw top-level-link

# This is the commit message #31:

add s3select submodule (remove s3select header files from src/rgw )

# This is the commit message #32:

re shape the document; mainly user oriented ; design & architecture is out (different document) ; TBD detailed example.

SUMMARY: AddressSanitizer: heap-use-after-free (/usr/bin/ceph-osd+0x1f6d5172) in crimson::osd::operator<<(std::ostream&, crimson::osd::PG const&)
```

Signed-off-by: Matan Breizman <mbreizma@redhat.com>
Matan-B added a commit to Matan-B/ceph that referenced this pull request Nov 8, 2023

SUMMARY: AddressSanitizer: heap-use-after-free (/usr/bin/ceph-osd+0x1f6d5172) in crimson::osd::operator<<(std::ostream&, crimson::osd::PG const&)
```

Signed-off-by: Matan Breizman <mbreizma@redhat.com>
Matan-B added a commit to Matan-B/ceph that referenced this pull request Nov 8, 2023

SUMMARY: AddressSanitizer: heap-use-after-free (/usr/bin/ceph-osd+0x1f6d5172) in crimson::osd::operator<<(std::ostream&, crimson::osd::PG const&)
```

Signed-off-by: Matan Breizman <mbreizma@redhat.com>
Matan-B added a commit to Matan-B/ceph that referenced this pull request Nov 9, 2023
Beacuse the loop's returned future is ignored,
we should cover the scenario where the pg is removed and the
snap_trimq iteration didn't complete yet.

Fixes: https://tracker.ceph.com/issues/61653

vec.push_back(str) will allocate memory and release the old one once
there is insufficient memory which causing the old one to be invalid. So
streambuf's data pointer and insertion position should be updated to
newly allocated memory's address in vec.

newly allocated memory's address in vec.

newly allocated memory's address in vec.

SUMMARY: AddressSanitizer: 2 byte(s) leaked in 2 allocation(s).
```

tchaikov added a commit to tchaikov/ceph that referenced this pull request Jun 3, 2025
Previously, SyncPoint allocated two C_Gather instances tracked by raw
pointers but failed to properly clean them up when only a single sync
point existed, causing memory leaks detected by AddressSanitizer.

This change fixes the leak by modifying AbstractWriteLog::shut_down()
to check for prior sync points in the chain. When the current sync point
is the only one present, we now activate the m_prior_log_entries_persisted
context to ensure:

- The onfinish callback executes and releases the captured strong
  reference to the enclosing SyncPoint
- The parent m_sync_point_persist context completes and gets properly
  released

This ensures all allocated contexts are cleaned up correctly during
shutdown, eliminating the memory leak.

The ASan report:

Previously, SyncPoint allocated two C_Gather instances tracked by raw
pointers but failed to properly clean them up when only a single sync
point existed, causing memory leaks detected by AddressSanitizer.

This change fixes the leak by modifying AbstractWriteLog::shut_down()
to check for prior sync points in the chain. When the current sync point
is the only one present, we now activate the m_prior_log_entries_persisted
context to ensure:

- The onfinish callback executes and releases the captured strong
  reference to the enclosing SyncPoint
- The parent m_sync_point_persist context completes and gets properly
  released

This ensures all allocated contexts are cleaned up correctly during
shutdown, eliminating the memory leak.

Previously, SyncPoint allocated two C_Gather instances tracked by raw
pointers but failed to properly clean them up when only a single sync
point existed, causing memory leaks detected by AddressSanitizer.

This change fixes the leak by modifying AbstractWriteLog::shut_down()
to check for prior sync points in the chain. When the current sync point
is the only one present, we now activate the m_prior_log_entries_persisted
context to ensure:

- The onfinish callback executes and releases the captured strong
  reference to the enclosing SyncPoint
- The parent m_sync_point_persist context completes and gets properly
  released

This ensures all allocated contexts are cleaned up correctly during
shutdown, eliminating the memory leak.

Add suppression rules for two categories of false positive warnings
encountered during ASan-enabled testing:

1. PyModule_ExecDef memory leaks: ASan incorrectly interprets Python's
   module loading behavior as memory leaks when the interpreter loads
   extension modules.

2. __cxa_throw interception failures: ASan's interceptor cannot properly
   intercept exception handling when libstdc++.so is loaded after the
   ASan shared library, causing CHECK failures.

3. ErasureCodePluginRegistry:add leakage: this suppression rule is
   copied from qa/valgrind.supp.

All warnings are confirmed false positives that should be suppressed
to reduce noise in test output.

Example warnings:

   module loading behavior as memory leaks when the interpreter loads
   extension modules.

2. __cxa_throw interception failures: ASan's interceptor cannot properly
   intercept exception handling when libstdc++.so is loaded after the
   ASan shared library, causing CHECK failures.

3. ErasureCodePluginRegistry::load:
   `ceph::ErasureCodePluginRegistry::load()` is known to leak, as we
   don't free the memory allocated by the ec plugins which are
   registered in the `ErasureCodePluginRegistry` singleton. this is a
   known issue, but since the `ErasureCodePluginRegistry` instance is a
   singleton. we can live with it. in this change, we add the rule to
   suppress the leak report from LeakSanitizer. this rule also exist in
   qa/valgrind.supp.

All warnings are confirmed false positives that should be suppressed
to reduce noise in test output.

Add suppression rules for two categories of false positive warnings
encountered during ASan-enabled testing:

1. PyModule_ExecDef memory leaks: ASan incorrectly interprets Python's
   module loading behavior as memory leaks when the interpreter loads
   extension modules.

2. __cxa_throw interception failures: ASan's interceptor cannot properly
   intercept exception handling when libstdc++.so is loaded after the
   ASan shared library, causing CHECK failures.

3. ErasureCodePluginRegistry::load:
   `ceph::ErasureCodePluginRegistry::load()` is known to leak, as we
   don't free the memory allocated by the ec plugins which are
   registered in the `ErasureCodePluginRegistry` singleton. this is a
   known issue, but since the `ErasureCodePluginRegistry` instance is a
   singleton. we can live with it. in this change, we add the rule to
   suppress the leak report from LeakSanitizer. this rule also exist in
   qa/valgrind.supp.

All warnings are confirmed false positives that should be suppressed
to reduce noise in test output.

Currently, *all* MGRs collectively segfault on Ceph v19.2.3 running on
Debian Trixie if a client requests the removal of an RBD image from
the RBD trash (ceph#6635 [0]).

After a lot of investigation, the cause of this still isn't clear to
me; the most likely culprit are some internal changes to Python
sub-interpreters that happened between Python versions 3.12 and 3.13.

What leads me to this conclusion is the following:
 1. A user on our forum noted [1] that the issue disappeared as soon
    as they set up a Ceph MGR inside a Debian Bookworm VM. Bookworm
    has Python version 3.11, which is the version before any
    substantial changes to sub-interpreters [2][3] were made.

 2. There is an upstream issue [4] regarding another segfault during
    MGR startup. The author concluded that this problem is related to
    sub-interpreters and opened another issue [5] on Python's issue
    tracker that goes into more detail.

    Even though this is for a completely different code path, it shows
    that issues related to sub-interpreters are popping up elsewhere
    at the very least.

 3. The segfault happens *inside* the Python interpreter:

    ceph#29 0x000078e04d91a7b8 __clone3 (libc.so.6 + 0x1107b8)

    Note that in ceph#12, you can see that a "progress callback" is being
    called by librbd. This callback is a plain Python function that is
    passed down via Ceph's Python/C++ bindings for librbd [6].
    (I'd provide more stack traces for the other threads here, but
    they're rather massive.)

    Then, from ceph#11 to ceph#4 the entire execution happens within the
    Python interpreter: This is just the callback being executed.
    The segfault happens at ceph#4 during _Py_dict_lookup(), which is a
    private function inside the Python interpreter to look something
    up in a `dict` [7]. As this function is so fundamental, it
    shouldn't ever fail, ever; but yet it does, which suggests that
    some internal interpreter state is most likely corrupted at that
    point.

Since it's incredibly hard to debug and actually figure out what the
*real* underlying issue is, simply disable that on_progress callback
instead. I just hope that this doesn't move the problem somewhere
else.

Unless I'm mistaken, there aren't any other callbacks that get passed
through C/C++ via Cython [8] like this, so this should hopefully
prevent any further SIGSEGVs until this is fixed upstream (somehow).

Note that this bug was also reported upstream [9].

Add suppression rules for two categories of false positive warnings
encountered during ASan-enabled testing:

1. PyModule_ExecDef memory leaks: ASan incorrectly interprets Python's
   module loading behavior as memory leaks when the interpreter loads
   extension modules.

2. __cxa_throw interception failures: ASan's interceptor cannot properly
   intercept exception handling when libstdc++.so is loaded after the
   ASan shared library, causing CHECK failures.

3. ErasureCodePluginRegistry::load:
   `ceph::ErasureCodePluginRegistry::load()` is known to leak, as we
   don't free the memory allocated by the ec plugins which are
   registered in the `ErasureCodePluginRegistry` singleton. this is a
   known issue, but since the `ErasureCodePluginRegistry` instance is a
   singleton. we can live with it. in this change, we add the rule to
   suppress the leak report from LeakSanitizer. this rule also exist in
   qa/valgrind.supp.

All warnings are confirmed false positives that should be suppressed
to reduce noise in test output.

Example warnings:

```

When co_waiter is destroyed, the cancellation slot may still hold a
reference to the op_cancellation callback which captures 'this'. If
the cancellation signal is emitted after co_waiter is destroyed (e.g.,
during co_throttle shutdown), it results in a stack-use-after-scope
error.

Fix by:
- Adding a cancel_slot member to store the cancellation slot
- Adding a destructor that clears the slot before destruction
- Modifying get() to store the slot for later cleanup

This ensures the cancellation callback is removed before the co_waiter
object goes out of scope, preventing use-after-scope errors.

rbd_features_from_string() uses boost::lexical_cast which throws
bad_lexical_cast when the input is not numeric. The exception is caught
and handled as "parse as feature name list instead".

This is normal control flow, but when ASAN's __cxa_throw interceptor is
misconfigured (e.g. with intercept_cxx_exceptions=0 leaving real___cxa_throw
NULL), any exception causes a CHECK failure. Even with a correctly configured
ASAN, throwing exceptions during config initialization adds overhead.

Replace the try/catch pattern with boost::conversion::try_lexical_convert,
which returns false on parse failure instead of throwing. This eliminates
the exception entirely, making the code more efficient and avoiding any
interaction with ASAN's exception interceptor.

The ASan report:
