From 75b23fa0a4916a228b2b66e73044378931862a49 Mon Sep 17 00:00:00 2001 From: Frantisek Sumsal Date: Sun, 30 Jan 2022 23:40:05 +0100 Subject: [PATCH] basic: update CIFS magic Kernel commit dea2903719283c156b53741126228c4a1b40440f exposed (and renamed) CIFS_MAGIC_NUMBER as CIFS_SUPER_MAGIC along with SMB2_SUPER_MAGIC. This fixes the following build fail on current Fedora Rawhide: ``` ../src/basic/meson.build:389:8: ERROR: Problem encountered: found unknown filesystem(s) defined in kernel headers: Filesystem found in kernel header but not in filesystems-gperf.gperf: CIFS_SUPER_MAGIC Filesystem found in kernel header but not in filesystems-gperf.gperf: SMB2_SUPER_MAGIC ``` (cherry picked from commit bbe53713455be38c0a587626439fd171f28c77fc) Related: #2017035 --- src/basic/filesystems-gperf.gperf | 4 ++-- src/basic/missing_magic.h | 11 ++++++++--- 2 files changed, 10 insertions(+), 5 deletions(-) diff --git a/src/basic/filesystems-gperf.gperf b/src/basic/filesystems-gperf.gperf index 08c8c44510..e8c5357f91 100644 --- a/src/basic/filesystems-gperf.gperf +++ b/src/basic/filesystems-gperf.gperf @@ -40,7 +40,7 @@ ceph, {CEPH_SUPER_MAGIC} cgroup2, {CGROUP2_SUPER_MAGIC} # note that the cgroupfs magic got reassigned from cpuset cgroup, {CGROUP_SUPER_MAGIC} -cifs, {CIFS_MAGIC_NUMBER} +cifs, {CIFS_SUPER_MAGIC, SMB2_SUPER_MAGIC} coda, {CODA_SUPER_MAGIC} configfs, {CONFIGFS_MAGIC} cramfs, {CRAMFS_MAGIC} @@ -109,7 +109,7 @@ selinuxfs, {SELINUX_MAGIC} shiftfs, {SHIFTFS_MAGIC} smackfs, {SMACK_MAGIC} # smb3 is an alias for cifs -smb3, {CIFS_MAGIC_NUMBER} +smb3, {CIFS_SUPER_MAGIC} # smbfs was removed from the kernel in 2010, the magic remains smbfs, {SMB_SUPER_MAGIC} sockfs, {SOCKFS_MAGIC} diff --git a/src/basic/missing_magic.h b/src/basic/missing_magic.h index 7d9320bb6d..c104fcfba3 100644 --- a/src/basic/missing_magic.h +++ b/src/basic/missing_magic.h @@ -38,9 +38,14 @@ #define XFS_SB_MAGIC 0x58465342 #endif -/* Not exposed yet.
