From fbd314e29d27cb38f56e528ef06fde2b96daf7d1 Mon Sep 17 00:00:00 2001 From: Steve French Date: Thu, 28 Jun 2018 18:46:40 -0500 Subject: [PATCH] cifs: add missing debug entries for kconfig options 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 Reviewed-by: Ronnie Sahlberg Reviewed-by: Pavel Shilovsky Reviewed-by: Paulo Alcantara CC: Stable Signed-off-by: Greg Kroah-Hartman --- fs/cifs/cifs_debug.c | 30 +++++++++++++++++++++++------- 1 file changed, 23 insertions(+), 7 deletions(-) diff --git a/fs/cifs/cifs_debug.c b/fs/cifs/cifs_debug.c index 3d03e48..ad8bd96 100644 --- a/fs/cifs/cifs_debug.c +++ b/fs/cifs/cifs_debug.c @@ -123,25 +123,41 @@ static int cifs_debug_data_proc_show(struct seq_file *m, void *v) 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); -- 2.7.4
