wasn't able to reproduce under vstart. tested both with a debug build and a release build
required extra storage-class configuration to run the lifecycle transition tests:
~/ceph/build $ bin/radosgw-admin zonegroup placement add --placement-id default-placement --storage-class FROZEN ~/ceph/build $ bin/radosgw-admin zonegroup placement add --placement-id default-placement --storage-class LUKEWARM ~/ceph/build $ bin/radosgw-admin zone placement add --placement-id default-placement --storage-class FROZEN --data-pool default.rgw.frozen.data ~/ceph/build $ bin/radosgw-admin zone placement add --placement-id default-placement --storage-class LUKEWARM --data-pool default.rgw.lukewarm.data
(restart radosgw)
then uncomment storage_classes in s3tests.conf.SAMPLE:
## Storage classes #storage_classes = "LUKEWARM, FROZEN"

when testing the squid backport of end2end tracing https://github.com/ceph/ceph/pull/55625, i didn't see these crashes. https://pulpito.ceph.com/cbodley-2024-02-27_20:28:25-rgw-wip-cbodley-testing-distro-default-smithi/

saw an expiration crash in https://qa-proxy.ceph.com/teuthology/cbodley-2024-03-13_12:30:10-rgw-wip-cbodley-testing-distro-default-smithi/7596563/teuthology.log that has a stack trace. it might be related

hey Shreyansh and Soumya, any updates here? this is one urgent for the squid release

Hi Casey..have started looking into it. I couldn't reproduce this issue locally with simple lc/cloud transition tests. Shreyansh mentioned that the crashes were frequently observed when using s3tests. I will run those now and update.

- File ceph.client.0.log ceph.client.0.log added
With Valgrind enabled & lc_debug_interval set to `1`, the crash is not observed however in one of the runs a valgrind error "Leak_PossiblyLost" is reported possibly during cleanup -
Attaching valgrind log file of that RGW service

- Priority changed from Urgent to Immediate
Updated by Casey Bodley about 2 months ago
i opened https://github.com/ceph/ceph/pull/56368 with a partial revert of the rgw tracing changes from https://github.com/ceph/ceph/pull/52114
i consider that a last resort for squid if we aren't able to find a root cause. in the meantime, i'd like to verify that lifecycle runs are green against that branch. we can potentially reintroduce that commit in pieces as a way to bisect the issue

spotted a different lifecycle crash in the rgw/dbstore suite, which is interesting because no expiration/transition is involved:

There are some lifecycle tests (which include expiration) not marked as 'fails_on_dbstore'. I will skip those tests too and check if the issue occurs even with just applying lifecycle policy rules.

i pushed another branch that reverts the rest of the tracing changes in librados and messenger, and still hit the crash in http://qa-proxy.ceph.com/teuthology/cbodley-2024-03-22_01:09:02-rgw:lifecycle-wip-60682-all-distro-default-smithi/7615848/teuthology.log

i managed to catch a crash under gdb with a local vstart cluster. since this seems timing-related and didn't reproduce under valgrind in teuthology, i'm testing a release build (CMAKE_BUILD_TYUPE=RelWithDebInfo) and started vstart.sh without the -d for debug logging
here's the backtrace from gdb:
Thread 111 "lifecycle_thr_1" received signal SIGSEGV, Segmentation fault.

spotted a different lifecycle crash in the rgw/dbstore suite, which is interesting because no expiration/transition is involved:

from https://qa-proxy.ceph.com/teuthology/cbodley-2024-03-20_23:26:29-rgw-wip-cbodley-testing-distro-default-smithi/7614326/teuthology.logThere are some lifecycle tests (which include expiration) not marked as 'fails_on_dbstore'. I will skip those tests too and check if the issue occurs even with just applying lifecycle policy rules.
lc crashes when running dbstore suite are due to a bug in dbstore (https://github.com/soumyakoduri/ceph/commit/c20c2d2499eeb182ebffb1675950e42719735b5f) and unrelated to the original issue. Will post the fix for review.

Most of these crashes seem to be related to bucket obj.
Could you please clarify what will be the bucket_version in the else case below (https://github.com/ceph/ceph/blob/main/src/rgw/driver/rados/rgw_sal_rados.cc#L546)
int RadosBucket::load_bucket(const DoutPrefixProvider* dpp, optional_yield y)
{
int ret;
int ret;
RGWSI_MetaBackend_CtxParams bectx_params = RGWSI_MetaBackend_CtxParams_SObj();
RGWObjVersionTracker ep_ot;
..
..
} else {
ret = store->ctl()->bucket->read_bucket_instance_info(info.bucket, &info, y, dpp,
RGWBucketCtl::BucketInstance::GetParams()
.set_mtime(&mtime)
.set_attrs(&attrs)
.set_bectx_params(bectx_params));
}
if (ret != 0) {
return ret;
}bucket_version = ep_ot.read_version; <<<< Here ep_ot.read_version is uninitialized incase of else{}.. right?}
The new code added in 'lc' publish_reserve()->load_bucket(..) enters the else{} code path as info.bucket.bucket_id is not empty. Could it be that bucket_version here gets updated with incorrect read_version which may result in probable use_after_free of the bucket object in the cache at later point?

This crash in cloud-transition code is being tracked as part of https://tracker.ceph.com/issues/65251
Updated by Casey Bodley about 1 month ago
the lifecycle changes in https://github.com/ceph/ceph/pull/55657 seem to be responsible for the crash, but it's not clear exactly how. discussion continues in https://github.com/ceph/ceph/pull/55657#discussion_r1541310624
Updated by Krunal Chheda about 1 month ago
- Subject changed from lifecycle transition crashes since merge end-to-end tracing to lifecycle transition crashes since reloading bucket attrs for notification
As discussed https://github.com/ceph/ceph/pull/55657#discussion_r1541310624, removing the logic to reload the bucket inside the publish_reserve and expect the caller to reload the bucket before calling.

The cause for this issue seems to be due to multiple LC worker threads updating the same `bucket` handle, which is not thread-safe. When another `load_bucket()` call was added in `remove_expirted_obj` as part of https://github.com/ceph/ceph/pull/55657, multiple threads could update and overwrite the same ceph::buffer::list stored in `bucket->attrs` resulting in corruption at times.
