4Subject: [PATCH 5/7] Always use -O2 for compiling fork.c
5
6When compiling in thumb mode for arm with -Os gcc gives up since it can
7not find registers to spill. So we use -O2 option for compiling fork.c
8It may be addressable in gcc.

4Subject: [PATCH 6/7] ldso: limited support for $ORIGIN in rpath
5MIME-Version: 1.0
6Content-Type: text/plain; charset=UTF-8
7Content-Transfer-Encoding: 8bit
8
9Derived from:
10http://lists.busybox.net/pipermail/uclibc/2011-March/045003.html
11
12However, the above patch introduced '_dl_strchr' in ldso/ldso/dl-elf.c,
13and caused the following undefined referencing compiling error:
14
15 | .../libdl.a(libdl.os): In function `search_for_named_library':
16 | .../dl-elf.c:156: undefined reference to `_dl_strchr'
17 | collect2: error: ld returned 1 exit status
18
19This problem would be reproduced through compiling gdb in static mode
20using uclibc.
21
22So, add the definition of '_dl_strchr' to fix it. The '_dl_strstr' is
23added as well.

12System based on Buildroot 2014.11
13 Linux 3.10.88
14 uclibc 0.9.33.2 (also with 1.0.2)
15 systemd 216
16 gcc 4.8.3 (also with 4.9.2)
17
18Bug:
19 After 2 days system is out of memory. PID 1 (systemd) is allocating.
20 over 120MB od RAM..
21 Just after reboot PID 1 is taking only about 600kB.
22
23How to reproduce:
24 With every systemd service reload or restart, heap of PID 1 grows.
25 Try with command:
26 watch -n1 \
27 'systemctl stop systemd-sysctl ; grep heap /proc/1/smaps -A15; free'
28
29Source of bug:
30
31 Uclibc's canonicalize_file_name() is allocating temprary buffer of.
32 4kB (PATH_MAX), and passing it to realpath() as second argument..
33 Function canonicalize... is not checking if realpath() fails and.
34 memory is lost.
35
36 Backtrace:
37 #0 malloc (bytes=4096) at libc/stdlib/malloc-standard/malloc.c:844
38 #1 canonicalize_file_name.
39 (name="/etc/systemd/system/systemd-sysctl.service.d") at.
40 libc/stdlib/canonicalize.c:30
41 #2 path_strv_resolve (...) at src/shared/path-util.c:275
42
43Solution:
44 Do not use temporary buffer like in eglibc.
45 Function realpath() will be responsible for allocation.
