+Subject: [PATCH v3] proc: fix missing pde_set_flags() for net proc files
+Date: Thu, 21 Aug 2025 18:58:06 +0800	[thread overview]
+Message-ID: <20250821105806.1453833-1-wangzijie1@honor.com> (raw)
+
+To avoid potential UAF issues during module removal races, we use pde_set_flags()
+to save proc_ops flags in PDE itself before proc_register(), and then use
+pde_has_proc_*() helpers instead of directly dereferencing pde->proc_ops->*.
+
+However, the pde_set_flags() call was missing when creating net related proc files.
+This omission caused incorrect behavior which FMODE_LSEEK was being cleared
+inappropriately in proc_reg_open() for net proc files. Lars reported it in this link[1].
+
+Fix this by ensuring pde_set_flags() is called when register proc entry, and add
+NULL check for proc_ops in pde_set_flags().
+
+[1]: https://lore.kernel.org/all/20250815195616.64497967@chagall.paradoxon.rec/
+
+Fixes: ff7ec8dc1b64 ("proc: use the same treatment to check proc_lseek as ones for proc_read_iter et.al")
+Cc: stable@vger.kernel.org
