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

nilfs2: fix potential deadlock with newly created symlinks

Syzbot reported that pagesymlink(), called by nilfssymlink(), triggers memory reclamation involving the filesystem layer, which can result in circular lock dependencies among the reader/writer semaphore nilfs->nssegctorsem, swriters percpurwsem (intwrite) and the fsreclaim pseudo lock.

This is because after commit 21fc61c73c39 ("don't put symlink bodies in pagecache into highmem"), the gfp flags of the page cache for symbolic links are overwritten to GFPKERNEL via inodenohighmem().

This is not a problem for symlinks read from the backing device, because the GFPFS flag is dropped after inodenohighmem() is called. However, when a new symlink is created with nilfssymlink(), the gfp flags remain overwritten to GFPKERNEL. Then, memory allocation called from pagesymlink() etc. triggers memory reclamation including the FS layer, which may call nilfsevictinode() or nilfsdirtyinode(). And these can cause a deadlock if they are called while nilfs->nssegctorsem is held:

Fix this issue by dropping the GFPFS flag from the page cache GFP flags of newly created symlinks in the same way that nilfsnewinode() and nilfsreadinode() do, as a workaround until we adopt nofs allocation scope consistently or improve the locking constraints.
