The patch titled serial: fixup /proc/tty/driver/serial after proc_fops conversion has been removed from the -mm tree. Its filename was serial-fixup-proc-tty-driver-serial-after-proc_fops-conversion.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: serial: fixup /proc/tty/driver/serial after proc_fops conversion From: Alexey Dobriyan <adobriyan@xxxxxxxxx> "struct tty_driver *" lies in m->private not in v which is SEQ_TOKEN_START which is 1 which is enough to trigger NULL dereference next line: BUG: unable to handle kernel NULL pointer dereference at 000000ad IP: [<c040d689>] uart_proc_show+0xe/0x2b0 Signed-off-by: Alexey Dobriyan <adobriyan@xxxxxxxxx> Reported-by: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx> Cc: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>a Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- drivers/serial/serial_core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff -puN drivers/serial/serial_core.c~serial-fixup-proc-tty-driver-serial-after-proc_fops-conversion drivers/serial/serial_core.c --- a/drivers/serial/serial_core.c~serial-fixup-proc-tty-driver-serial-after-proc_fops-conversion +++ a/drivers/serial/serial_core.c @@ -1765,7 +1765,7 @@ static void uart_line_info(struct seq_fi static int uart_proc_show(struct seq_file *m, void *v) { - struct tty_driver *ttydrv = v; + struct tty_driver *ttydrv = m->private; struct uart_driver *drv = ttydrv->driver_state; int i; _ Patches currently in -mm which might be from adobriyan@xxxxxxxxx are origin.patch linux-next.patch sysctl-dont-take-the-use-count-of-multiple-heads-at-a-time.patch sysctl-lockdep-support-for-sysctl-reference-counting.patch simplify-copy_thread.patch simplify-copy_thread-checkpatch-fixes.patch softirq-introduce-statistics-for-softirq.patch proc-export-statistics-for-softirq-to-proc.patch proc-export-statistics-for-softirq-to-proc-fix.patch proc-update-document-for-proc-softirqs-and-proc-stat.patch proc_sysctl-use-config_proc_sysctl-around-ipc-and-utsname-proc_handlers.patch sysctl-fix-suid_dumpable-and-lease-break-time-sysctls.patch namespaces-move-proc_net_get_sb-to-a-generic-fs-superc-helper.patch namespaces-move-proc_net_get_sb-to-a-generic-fs-superc-helper-fix.patch namespaces-mqueue-ns-move-mqueue_mnt-into-struct-ipc_namespace.patch namespaces-ipc-namespaces-implement-support-for-posix-msqueues.patch namespaces-ipc-namespaces-implement-support-for-posix-msqueues-initialize-init_ipc_nscount-to-1.patch namespaces-mqueue-namespace-adapt-sysctl.patch namespaces-mqueue-namespace-adapt-sysctl-update.patch namespaces-mqueue-namespace-adapt-sysctl-update-fix.patch -- To unsubscribe from this list: send the line "unsubscribe mm-commits" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
