From 9c937dcc71021f2dbf78f904f03d962dd9bcc130 Mon Sep 17 00:00:00 2001 From: Amy Griffis Date: Thu, 8 Jun 2006 23:19:31 -0400 Subject: [PATCH] log more info for directory entry change events When an audit event involves changes to a directory entry, include a PATH record for the directory itself. A few other notable changes: - fixed audit_inode_child() hooks in fsnotify_move() - removed unused flags arg from audit_inode() - added audit log routines for logging a portion of a string Here's some sample output. before patch: type=SYSCALL msg=audit(1149821605.320:26): arch=40000003 syscall=39 success=yes exit=0 a0=bf8d3c7c a1=1ff a2=804e1b8 a3=bf8d3c7c items=1 ppid=739 pid=800 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=ttyS0 comm="mkdir" exe="/bin/mkdir" subj=root:system_r:unconfined_t:s0-s0:c0.c255 type=CWD msg=audit(1149821605.320:26): cwd="/root" type=PATH msg=audit(1149821605.320:26): item=0 name="foo" parent=164068 inode=164010 dev=03:00 mode=040755 ouid=0 ogid=0 rdev=00:00 obj=root:object_r:user_home_t:s0 after patch: type=SYSCALL msg=audit(1149822032.332:24): arch=40000003 syscall=39 success=yes exit=0 a0=bfdd9c7c a1=1ff a2=804e1b8 a3=bfdd9c7c items=2 ppid=714 pid=777 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=ttyS0 comm="mkdir" exe="/bin/mkdir" subj=root:system_r:unconfined_t:s0-s0:c0.c255 type=CWD msg=audit(1149822032.332:24): cwd="/root" type=PATH msg=audit(1149822032.332:24): item=0 name="/root" inode=164068 dev=03:00 mode=040750 ouid=0 ogid=0 rdev=00:00 obj=root:object_r:user_home_dir_t:s0 type=PATH msg=audit(1149822032.332:24): item=1 name="foo" inode=164010 dev=03:00 mode=040755 ouid=0 ogid=0 rdev=00:00 obj=root:object_r:user_home_t:s0 Signed-off-by: Amy Griffis Signed-off-by: Al Viro --- include/linux/audit.h | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-) (limited to 'include/linux/audit.h') diff --git a/include/linux/audit.h b/include/linux/audit.h index c78327507f4e..e1c1dbdf9efb 100644 --- a/include/linux/audit.h +++ b/include/linux/audit.h @@ -310,7 +310,7 @@ extern void audit_syscall_entry(int arch, extern void audit_syscall_exit(int failed, long return_code); extern void __audit_getname(const char *name); extern void audit_putname(const char *name); -extern void __audit_inode(const char *name, const struct inode *inode, unsigned flags); +extern void __audit_inode(const char *name, const struct inode *inode); extern void __audit_inode_child(const char *dname, const struct inode *inode, unsigned long pino); static inline void audit_getname(const char *name) @@ -318,10 +318,9 @@ static inline void audit_getname(const char *name) if (unlikely(current->audit_context)) __audit_getname(name); } -static inline void audit_inode(const char *name, const struct inode *inode, - unsigned flags) { +static inline void audit_inode(const char *name, const struct inode *inode) { if (unlikely(current->audit_context)) - __audit_inode(name, inode, flags); + __audit_inode(name, inode); } static inline void audit_inode_child(const char *dname, const struct inode *inode, @@ -398,9 +397,9 @@ static inline int audit_mq_getsetattr(mqd_t mqdes, struct mq_attr *mqstat) #define audit_syscall_exit(f,r) do { ; } while (0) #define audit_getname(n) do { ; } while (0) #define audit_putname(n) do { ; } while (0) -#define __audit_inode(n,i,f) do { ; } while (0) +#define __audit_inode(n,i) do { ; } while (0) #define __audit_inode_child(d,i,p) do { ; } while (0) -#define audit_inode(n,i,f) do { ; } while (0) +#define audit_inode(n,i) do { ; } while (0) #define audit_inode_child(d,i,p) do { ; } while (0) #define auditsc_get_stamp(c,t,s) do { BUG(); } while (0) #define audit_get_loginuid(c) ({ -1; }) @@ -435,6 +434,9 @@ extern void audit_log_hex(struct audit_buffer *ab, size_t len); extern const char * audit_log_untrustedstring(struct audit_buffer *ab, const char *string); +extern const char * audit_log_n_untrustedstring(struct audit_buffer *ab, + size_t n, + const char *string); extern void audit_log_d_path(struct audit_buffer *ab, const char *prefix, struct dentry *dentry, @@ -452,6 +454,7 @@ extern int audit_receive_filter(int type, int pid, int uid, int seq, #define audit_log_end(b) do { ; } while (0) #define audit_log_hex(a,b,l) do { ; } while (0) #define audit_log_untrustedstring(a,s) do { ; } while (0) +#define audit_log_n_untrustedstring(a,n,s) do { ; } while (0) #define audit_log_d_path(b,p,d,v) do { ; } while (0) #endif #endif -- cgit v1.2.3
