jfs: add check read-only before truncation in jfs_truncate_nolock()

CVE-2024-58094

Description

In the Linux kernel, the following vulnerability has been resolved:

jfs: add check read-only before truncation in jfs_truncate_nolock()

Added a check for "read-only" mode in the jfs_truncate_nolock function to avoid errors related to writing to a read-only filesystem.

Call stack:

block_write_begin() { jfs_write_failed() { jfs_truncate() { jfs_truncate_nolock() { txEnd() { ... log = JFS_SBI(tblk->sb)->log; // (log == NULL)

If the isReadOnly(ip) condition is triggered in jfs_truncate_nolock, the function execution will stop, and no further data modification will occur. Instead, the xtTruncate function will be called with the "COMMIT_WMAP" flag, preventing modifications in "read-only" mode.
