[PATCH OLK-6.6] nfsd: don't ignore the return code of svc_proc_register()
by Li Lingfeng 27 Nov '25

27 Nov '25

From: Jeff Layton <jlayton(a)kernel.org> mainline inclusion from mainline-v6.15-rc1 commit 930b64ca0c511521f0abdd1d57ce52b2a6e3476b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC1QT8 CVE: CVE-2025-22026 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Currently, nfsd_proc_stat_init() ignores the return value of svc_proc_register(). If the procfile creation fails, then the kernel will WARN when it tries to remove the entry later. Fix nfsd_proc_stat_init() to return the same type of pointer as svc_proc_register(), and fix up nfsd_net_init() to check that and fail the nfsd_net construction if it occurs. svc_proc_register() can fail if the dentry can't be allocated, or if an identical dentry already exists. The second case is pretty unlikely in the nfsd_net construction codepath, so if this happens, return -ENOMEM.
