Title
ext4: fix i_data_sem unlock order in ext4_ind_migrate()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix i_data_sem unlock order in ext4_ind_migrate()
Fuzzing reports a possible deadlock in jbd2_log_wait_commit.
This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to require
synchronous updates because the file descriptor is opened with O_SYNC.
This can lead to the jbd2_journal_stop() function calling
jbd2_might_wait_for_commit(), potentially causing a deadlock if the
EXT4_IOC_MIGRATE call races with a write(2) system call.
This problem only arises when CONFIG_PROVE_LOCKING is enabled. In this
case, the jbd2_might_wait_for_commit macro locks jbd2_handle in the
jbd2_journal_stop function while i_data_sem is locked. This triggers
lockdep because the jbd2_journal_start function might also lock the same
jbd2_handle simultaneously.
Found by Linux Verification Center (linuxtesting.org) with syzkaller.

Esto puede provocar que la funci\u00f3n jbd2_journal_stop() llame a jbd2_might_wait_for_commit(), lo que puede provocar un bloqueo si la llamada a EXT4_IOC_MIGRATE compite con una llamada del sistema write(2). Este problema solo surge cuando CONFIG_PROVE_LOCKING est\u00e1 habilitado. En este caso, la macro jbd2_might_wait_for_commit bloquea jbd2_handle en la funci\u00f3n jbd2_journal_stop mientras i_data_sem est\u00e1 bloqueado. Esto activa lockdep porque la funci\u00f3n jbd2_journal_start tambi\u00e9n podr\u00eda bloquear el mismo jbd2_handle simult\u00e1neamente.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
