From: Li RongQing <roy.qing.li@xxxxxxxxx> although NFS_MAXPATHLEN is defined to 1024, nfs client hopes to accept a 1024 byte path, but nfs_root_parms is limited to 256, and the nfs path will truncated when a user inputs nfs path from kernel cmdline enlarge nfs_root_parms to 1024, to make it accept the 1024 bytes long directory name, since nfs_root_parms is defined as _initdata, it will be released after system bootup Signed-off-by: Li RongQing <roy.qing.li@xxxxxxxxx> --- fs/nfs/nfsroot.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/nfs/nfsroot.c b/fs/nfs/nfsroot.c index 9bc9f04..89a15db 100644 --- a/fs/nfs/nfsroot.c +++ b/fs/nfs/nfsroot.c @@ -90,7 +90,7 @@ #define NFS_DEF_OPTIONS "vers=2,udp,rsize=4096,wsize=4096" /* Parameters passed from the kernel command line */ -static char nfs_root_parms[256] __initdata = ""; +static char nfs_root_parms[NFS_MAXPATHLEN + 1] __initdata = ""; /* Text-based mount options passed to super.c */ static char nfs_root_options[256] __initdata = NFS_DEF_OPTIONS; -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
