[PATCH] security/apparmor: allow matching on presence of extended attributes

by Eric Chiang

Currently, xattrs values must match the xmatch DFA to match a profile. This lets users construct profiles to match a file with a specific key and value with a basic regex. profile test xattrs(security.apparmor=/usr/bin/*) {} The xmatch DFA doesn't handle null characters in the xattrs value, since this is the special character used to indicate that the DFA is transitioning from matching the profile path to matching the xattr value. However, both IMA and EVM xattr values hold signatures which potentially have a null character. It's currently impossible to write a profile that requires a the presence of an EVM signature without checking the value. profile test xattrs(security.evm security.apparmor=/usr/bin/*) {} Add an additional "xattr_keys" array to the profile that only checks the presence of extended attributes, and not their values. A modified apparmor_parser that was used to test these changes can be found at: https://gitlab.com/ericchiang/apparmor/commits/parser-xattrs-keys To test, build the parser and run the following command: $ echo '/usr/bin/* xattrs=(user.foo user.bar=bar) {}' | \ ./apparmor_parser -r $ setfattr -n "user.foo" -v "foo" /usr/bin/whoami $ setfattr -n "user.bar" -v "bar" /usr/bin/whoami $ whoami # command fails Signed-off-by: Eric Chiang <ericchiang(a)google.com> CC: stable(a)vger.kernel.org --- security/apparmor/domain.c | 22 +++++++++++++++++++--- security/apparmor/include/policy.h | 6 ++++++ security/apparmor/policy.c | 3 +++ security/apparmor/policy_unpack.c | 18 ++++++++++++++++++ 4 files changed, 46 insertions(+), 3 deletions(-) diff --git a/security/apparmor/domain.c b/security/apparmor/domain.c index 08c88de0ffda..53c46e3e01f0 100644 --- a/security/apparmor/domain.c +++ b/security/apparmor/domain.c @@ -319,14 +319,30 @@ static int aa_xattrs_match(const struct linux_binprm *bprm, char *value = NULL; int value_size = 0, ret = profile->xattr_count; - if (!bprm || !profile->xattr_count) + if (!bprm) return 0; + d = bprm->file->f_path.dentry; + + if (profile->xattr_keys_count) { + /* validate that these attributes are present, ignore values */ + for (i = 0; i < profile->xattr_keys_count; i++) { + size = vfs_getxattr_alloc(d, profile->xattr_keys[i], + &value, value_size, + GFP_KERNEL); + if (size < 0) { + ret = -EINVAL; + goto out; + } + } + } + + if (!profile->xattr_count) + goto out; + /* transition from exec match to xattr set */ state = aa_dfa_null_transition(profile->xmatch, state); - d = bprm->file->f_path.dentry; - for (i = 0; i < profile->xattr_count; i++) { size = vfs_getxattr_alloc(d, profile->xattrs[i], &value, value_size, GFP_KERNEL); diff --git a/security/apparmor/include/policy.h b/security/apparmor/include/policy.h index 8e6707c837be..8ed1d30de7ce 100644 --- a/security/apparmor/include/policy.h +++ b/security/apparmor/include/policy.h @@ -112,6 +112,10 @@ struct aa_data { * @policy: general match rules governing policy * @file: The set of rules governing basic file access and domain transitions * @caps: capabilities for the profile + * @xattr_count: number of xattrs values + * @xattrs: extended attributes whose values must match the xmatch + * @xattr_keys_count: number of xattr keys values + * @xattr_keys: extended attributes that must be present to match the profile * @rlimits: rlimits for the profile * * @dents: dentries for the profiles file entries in apparmorfs @@ -152,6 +156,8 @@ struct aa_profile { int xattr_count; char **xattrs; + int xattr_keys_count; + char **xattr_keys; struct aa_rlimit rlimits; diff --git a/security/apparmor/policy.c b/security/apparmor/policy.c index df9c5890a878..e0f9cf8b8318 100644 --- a/security/apparmor/policy.c +++ b/security/apparmor/policy.c @@ -231,6 +231,9 @@ void aa_free_profile(struct aa_profile *profile) for (i = 0; i < profile->xattr_count; i++) kzfree(profile->xattrs[i]); kzfree(profile->xattrs); + for (i = 0; i < profile->xattr_keys_count; i++) + kzfree(profile->xattr_keys[i]); + kzfree(profile->xattr_keys); for (i = 0; i < profile->secmark_count; i++) kzfree(profile->secmark[i].label); kzfree(profile->secmark); diff --git a/security/apparmor/policy_unpack.c b/security/apparmor/policy_unpack.c index 379682e2a8d5..d1fd75093260 100644 --- a/security/apparmor/policy_unpack.c +++ b/security/apparmor/policy_unpack.c @@ -535,6 +535,24 @@ static bool unpack_xattrs(struct aa_ext *e, struct aa_profile *profile) goto fail; } + if (unpack_nameX(e, AA_STRUCT, "xattr_keys")) { + int i, size; + + size = unpack_array(e, NULL); + profile->xattr_keys_count = size; + profile->xattr_keys = kcalloc(size, sizeof(char *), GFP_KERNEL); + if (!profile->xattr_keys) + goto fail; + for (i = 0; i < size; i++) { + if (!unpack_strdup(e, &profile->xattr_keys[i], NULL)) + goto fail; + } + if (!unpack_nameX(e, AA_ARRAYEND, NULL)) + goto fail; + if (!unpack_nameX(e, AA_STRUCTEND, NULL)) + goto fail; + } + return 1; fail: -- 2.20.0.rc2.403.gdbc3b29805-goog

The underlying reason was that the HWPoison page has an elevated reference count and the migration keeps failing. There are two problems with that. First of all it is dubious to migrate the poisoned page because we know that accessing that memory is possible to fail. Secondly it doesn't make any sense to migrate a potentially broken content and preserve the memory corruption over to a new location. Oscar has found out that 4.4 and the current upstream kernels behave slightly differently with his simply testcase === int main(void) { int ret; int i; int fd; char *array = malloc(4096); char *array_locked = malloc(4096); fd = open("/tmp/data", O_RDONLY); read(fd, array, 4095); for (i = 0; i < 4096; i++) array_locked[i] = 'd'; ret = mlock((void *)PAGE_ALIGN((unsigned long)array_locked), sizeof(array_locked)); if (ret) perror("mlock"); sleep (20); ret = madvise((void *)PAGE_ALIGN((unsigned long)array_locked), 4096, MADV_HWPOISON); if (ret) perror("madvise"); for (i = 0; i < 4096; i++) array_locked[i] = 'd'; return 0; } === + offline this memory. In 4.4 kernels he saw the hwpoisoned page to be returned back to the LRU list kernel: [<ffffffff81019ac9>] dump_trace+0x59/0x340 kernel: [<ffffffff81019e9a>] show_stack_log_lvl+0xea/0x170 kernel: [<ffffffff8101ac71>] show_stack+0x21/0x40 kernel: [<ffffffff8132bb90>] dump_stack+0x5c/0x7c kernel: [<ffffffff810815a1>] warn_slowpath_common+0x81/0xb0 kernel: [<ffffffff811a275c>] __pagevec_lru_add_fn+0x14c/0x160 kernel: [<ffffffff811a2eed>] pagevec_lru_move_fn+0xad/0x100 kernel: [<ffffffff811a334c>] __lru_cache_add+0x6c/0xb0 kernel: [<ffffffff81195236>] add_to_page_cache_lru+0x46/0x70 kernel: [<ffffffffa02b4373>] extent_readpages+0xc3/0x1a0 [btrfs] kernel: [<ffffffff811a16d7>] __do_page_cache_readahead+0x177/0x200 kernel: [<ffffffff811a18c8>] ondemand_readahead+0x168/0x2a0 kernel: [<ffffffff8119673f>] generic_file_read_iter+0x41f/0x660 kernel: [<ffffffff8120e50d>] __vfs_read+0xcd/0x140 kernel: [<ffffffff8120e9ea>] vfs_read+0x7a/0x120 kernel: [<ffffffff8121404b>] kernel_read+0x3b/0x50 kernel: [<ffffffff81215c80>] do_execveat_common.isra.29+0x490/0x6f0 kernel: [<ffffffff81215f08>] do_execve+0x28/0x30 kernel: [<ffffffff81095ddb>] call_usermodehelper_exec_async+0xfb/0x130 kernel: [<ffffffff8161c045>] ret_from_fork+0x55/0x80 And that latter confuses the hotremove path because an LRU page is attempted to be migrated and that fails due to an elevated reference count. It is quite possible that the reuse of the HWPoisoned page is some kind of fixed race condition but I am not really sure about that. With the upstream kernel the failure is slightly different. The page doesn't seem to have LRU bit set but isolate_movable_page simply fails and do_migrate_range simply puts all the isolated pages back to LRU and therefore no progress is made and scan_movable_pages finds same set of pages over and over again. Fix both cases by explicitly checking HWPoisoned pages before we even try to get reference on the page, try to unmap it if it is still mapped. As explained by Naoya: : Hwpoison code never unmapped those for no big reason because : Ksm pages never dominate memory, so we simply didn't have strong : motivation to save the pages. Also put WARN_ON(PageLRU) in case there is a race and we can hit LRU HWPoison pages which shouldn't happen but I couldn't convince myself about that. Naoya has noted the following: : Theoretically no such gurantee, because try_to_unmap() doesn't have a : guarantee of success and then memory_failure() returns immediately : when hwpoison_user_mappings fails. : Or the following code (comes after hwpoison_user_mappings block) also impli= : es : that the target page can still have PageLRU flag. : : /* : * Torn down by someone else? : */ : if (PageLRU(p) && !PageSwapCache(p) && p->mapping =3D=3D NULL) { : action_result(pfn, MF_MSG_TRUNCATED_LRU, MF_IGNORED); : res =3D -EBUSY; : goto out; : } : : So I think it's OK to keep "if (WARN_ON(PageLRU(page)))" block in : current version of your patch.
