4.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Steve French <stfrench@xxxxxxxxxxxxx> commit 950132afd59385caf6e2b84e5235d069fa10681d upstream. /proc/fs/cifs/DebugData displays the features (Kconfig options) used to build cifs.ko but it was missing some, and needed comma separator. These can be useful in debugging certain problems so we know which optional features were enabled in the user's build. Also clarify them, by making them more closely match the corresponding CONFIG_CIFS_* parm. Old format: Features: dfs fscache posix spnego xattr acl New format: Features: DFS,FSCACHE,SMB_DIRECT,STATS,DEBUG2,ALLOW_INSECURE_LEGACY,CIFS_POSIX,UPCALL(SPNEGO),XATTR,ACL Signed-off-by: Steve French <stfrench@xxxxxxxxxxxxx> Reviewed-by: Ronnie Sahlberg <lsahlber@xxxxxxxxxx> Reviewed-by: Pavel Shilovsky <pshilov@xxxxxxxxxxxxx> Reviewed-by: Paulo Alcantara <palcantara@xxxxxxx> CC: Stable <stable@xxxxxxxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- fs/cifs/cifs_debug.c | 30 +++++++++++++++++++++++------- 1 file changed, 23 insertions(+), 7 deletions(-) --- a/fs/cifs/cifs_debug.c +++ b/fs/cifs/cifs_debug.c @@ -160,25 +160,41 @@ static int cifs_debug_data_proc_show(str seq_printf(m, "CIFS Version %s\n", CIFS_VERSION); seq_printf(m, "Features:"); #ifdef CONFIG_CIFS_DFS_UPCALL - seq_printf(m, " dfs"); + seq_printf(m, " DFS"); #endif #ifdef CONFIG_CIFS_FSCACHE - seq_printf(m, " fscache"); + seq_printf(m, ",FSCACHE"); +#endif +#ifdef CONFIG_CIFS_SMB_DIRECT + seq_printf(m, ",SMB_DIRECT"); +#endif +#ifdef CONFIG_CIFS_STATS2 + seq_printf(m, ",STATS2"); +#elif defined(CONFIG_CIFS_STATS) + seq_printf(m, ",STATS"); +#endif +#ifdef CONFIG_CIFS_DEBUG2 + seq_printf(m, ",DEBUG2"); +#elif defined(CONFIG_CIFS_DEBUG) + seq_printf(m, ",DEBUG"); +#endif +#ifdef CONFIG_CIFS_ALLOW_INSECURE_LEGACY + seq_printf(m, ",ALLOW_INSECURE_LEGACY"); #endif #ifdef CONFIG_CIFS_WEAK_PW_HASH - seq_printf(m, " lanman"); + seq_printf(m, ",WEAK_PW_HASH"); #endif #ifdef CONFIG_CIFS_POSIX - seq_printf(m, " posix"); + seq_printf(m, ",CIFS_POSIX"); #endif #ifdef CONFIG_CIFS_UPCALL - seq_printf(m, " spnego"); + seq_printf(m, ",UPCALL(SPNEGO)"); #endif #ifdef CONFIG_CIFS_XATTR - seq_printf(m, " xattr"); + seq_printf(m, ",XATTR"); #endif #ifdef CONFIG_CIFS_ACL - seq_printf(m, " acl"); + seq_printf(m, ",ACL"); #endif seq_putc(m, '\n'); seq_printf(m, "Active VFS Requests: %d\n", GlobalTotalActiveXid);
