Hi everyone, |
| 2 |
|
| 3 |
I recently saw the hardened musl project so I wanted to play with it for |
| 4 |
my router. |
| 5 |
|
| 6 |
My platform: CHOST="x86_64-gentoo-linux-musl" |
| 7 |
|
| 8 |
There is a list of ebuilds taken from official portage I modified to |
| 9 |
successfully compile for musl without breaking the compatibility with |
| 10 |
other CHOST: |
| 11 |
* app-admin/logrotate |
| 12 |
* app-misc/screen |
| 13 |
* net-analyzer/snort |
| 14 |
* net-firewall/arptables |
| 15 |
* net-firewall/ebtables |
| 16 |
* net-libs/daq |
| 17 |
* net-libs/libnetfiler_queue |
| 18 |
* net-libs/libnfnetlink |
| 19 |
* net-libs/libtirpc |
| 20 |
* net-misc/dhcp |
| 21 |
* net-misc/iperf |
| 22 |
* net-misc/openvpn-2.3.6 |
| 23 |
* sys-apps/hwinfo |
| 24 |
* sys-apps/iproute2 |
| 25 |
* sys-apps/lm_sensors |
| 26 |
* sys-apps/watchdog |
| 27 |
* sys-boot/grub:2 |
| 28 |
* sys-fs/btrfs-progs |
| 29 |
* sys-libs/musl |
| 30 |
* sys-process/lsof |
| 31 |
* www-servers/nginx |
| 32 |

I have modified libtirpc so it is the default rpc include files provider |
| 34 |
for musl. glibc and ulibc provides rpc, musl not. |
| 35 |
|
| 36 |
With recent releases of binutils, musl fail to correctly find libraries |
| 37 |
as described here: |
| 38 |
http://git.musl-libc.org/cgit/musl/commit/src/ldso/dynlink.c?id=d8dc2b7c0289b12eeef4feff65e3c918111b0f55 |
| 39 |
|
| 40 |
This is the case with /usr/bin/man provided in the current experimental |
| 41 |
stage3 where musl does not found libmandb or libman without the patch or |
| 42 |
without defining LD_LIBRARY_PATH: |
| 43 |
localhost kveer # ldd /usr/bin/man |
| 44 |
/lib/ld-musl-x86_64.so.1 (0x317c90c4000) |
| 45 |
libmandb-2.6.6.so => /usr/lib/man-db/libmandb-2.6.6.so |
| 46 |
(0x317c8ca1000) |
| 47 |
libman-2.6.6.so => /usr/lib/man-db/libman-2.6.6.so |
| 48 |
(0x317c8a68000) |
| 49 |
libpipeline.so.1 => /usr/lib/libpipeline.so.1 (0x317c8858000) |
| 50 |
libc.so => /lib/ld-musl-x86_64.so.1 (0x317c90c4000) |
| 51 |
libgdbm.so.4 => /usr/lib/libgdbm.so.4 (0x317c864c000) |
| 52 |
libz.so.1 => /lib/libz.so.1 (0x317c8434000) |
| 53 |
|
| 54 |
Finally, musl does not come with a distinct ldd tool and is missing on |
| 55 |
the stage3. As described by the musl maintener, ldd is available making |
| 56 |
a symbolic link to the main lib: |
| 57 |
localhost kveer # ll /usr/bin/ldd |
| 58 |
lrwxrwxrwx 1 root root 24 Dec 23 16:11 /usr/bin/ldd -> |
| 59 |
/lib/ld-musl-x86_64.so.1 |
| 60 |
|
| 61 |
For now, everything compiles fine but I don't know yet if all is working |
| 62 |
properly. |
| 63 |
|
| 64 |
I put everything on my personal repo here: |
| 65 |
https://github.com/LordVeovis/gentoo (starting from |
| 66 |
176c1d4dd1f7064d0c378e6b37034f7b604e04a2) but let me know how you want |
| 67 |
to proceed for all of this or if my way of patching is incorrect. |
