Not an issue for me since quite some time with a newer xorg stack (possibly
also due to upgrading to 10.x from 9.x).

[Bug 225162] Source file zfs_acl.c, function zfs_aclset_common contains a use after end of the lifetime of a local variable

2018-01-14 Thread bugzilla-noreply 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225162

--- Comment #1 from WHR  ---
Source file
https://svnweb.freebsd.org/base/head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zfs_acl.c
(latest version r323491 at this time), line 1220, in function zfs_aclset_common
have a local variable definition "zfs_acl_phys_t acl_phys;". At line 1297, the
pointer to this variable (_phys) is stored into the array "bulk"; then the
current code block and the lifetime of "acl_phys" is ended after this, but
"bulk" is still got used at line 1314.

This code resulted in undefined behavior, meaning this bug may not be generally
noticeable. In my test, the clang 3.4.1 on FreeBSD 10.3 amd64 won't trigger
wrong behavior; however gcc 4.7 4.8 4.9 at any optimization level (except
"-O0") will resulting a buggy behavior which showing to the user as:

[WHR@kmod-test /testpool]$ mkdir 35
[WHR@kmod-test /testpool]$ cd 35
-bash: cd: 35: Permission denied

Due the ACL is failed to store.

The attached patch will fix this bug by moving the definition of "acl_phys" to
the top block of the function, thus its lifetime will cover the whole function.

Bug ID: 225159
   Summary: `make installkernel’ should display a “completed”
message if done
   Product: Base System
   Version: CURRENT

OS: Any
Status: New
  Severity: Affects Only Me
  Priority: ---

If you build a kernel you will see in the log output some status messages as

$ make buildkernel
>>> Kernel build for GENERIC started on Sun Jan 14 05:03:57 PST 2018
>>> stage 1: configuring the kernel
[...]
>>> Kernel build for GENERIC completed on Sun Jan 14 05:54:22 PST 2018

If you see the message “Kernel build for GENERIC completed” then you know the
kernel was successfully build.

if you install the kernel

$ make installkernel
>>> Installing kernel GENERIC
[]
kldxref /boot/kernel

There is no  “Installing kernel GENERIC completed” message. It is not obvious
if the kernel installation was successfully.

BTW, we should also display the time when the kernel was installed, as we do
for the build.

> 9.3 is EOL. So i think this is overcome by events.
I think so. And also bug #206740 should be marked as such.
