Avoid integer overflow. +Use memcmp rather than strncmp to compare memory blocks. +(file_has_acl): Preserve initial errno instead of setting to 0. +Allocate a bit more room for trivial ACL buffer. +Use EINVAL for botchedk NFSv4 ACLs (which shouldn’t happen). + +Upstream-commit: 35bd46f0c816948dc1a0430c8ba8b10a01167320 +Signed-off-by: Kamil Dudka +--- + doc/acl-nfsv4.txt | 17 ------ + lib/acl-internal.c | 100 ----------------------------------- + lib/acl-internal.h | 3 -- + lib/file-has-acl.c | 129 +++++++++++++++++++++++++++++++++++++++------ + 4 files changed, 113 insertions(+), 136 deletions(-) + delete mode 100644 doc/acl-nfsv4.txt + +diff --git a/doc/acl-nfsv4.txt b/doc/acl-nfsv4.txt +deleted file mode 100644 +index 71352f5..0000000 +--- a/doc/acl-nfsv4.txt ++++ /dev/null +@@ -1,17 +0,0 @@ +-General introduction: +- https://linux.die.net/man/5/nfs4_acl +- +-The NFSv4 acls are defined in RFC7530 and as such, every NFSv4 server supporting ACLs +-will support this kind of ACLs (note the difference from POSIX draft ACLs) +- +-The ACLs can be obtained via the nfsv4-acl-tools, i.e. +- +-$ nfs4_getfacl +- +-# file: +-A::OWNER@:rwaDxtTnNcCy +-A::GROUP@:rwaDxtTnNcy +-A::EVERYONE@:rwaDxtTnNcy +- +-Gnulib is aiming to only provide a basic support of these, i.e. recognize trivial +-and non-trivial ACLs +diff --git a/lib/acl-internal.c b/lib/acl-internal.c +index 4c65dff..be244c6 100644 +--- a/lib/acl-internal.c ++++ b/lib/acl-internal.c +@@ -25,9 +25,6 @@ + + #if USE_ACL && HAVE_ACL_GET_FILE /* Linux, FreeBSD, Mac OS X, IRIX, Tru64, Cygwin >= 2.5 */ + +-# include +-# include +- + # if HAVE_ACL_TYPE_EXTENDED /* Mac OS X */ + + /* ACL is an ACL, from a file, stored as type ACL_TYPE_EXTENDED. +@@ -125,103 +122,6 @@ acl_default_nontrivial (acl_t acl) + return (acl_entries (acl) > 0);
