The other was mentioned as a possible requirement as well. I have not spent any time seeing whether its worth it or not to support libcap-ng. Do you know enough about them both to pick? It may be related to the LIBCAP_BROKEN identifier or another such test for the specific function may be worth adding... I rather have one code base than two here.. either libcap is used or it is not. Using libcap if found working or raw syscalls if not does not sound like a good idea to me. But maybe we can require a reasonably current libcap-2 for TPROXY support? It requires a custom kernel anyway on the systems with too old libcap implementations I think. We can do that yes. I think I would also rather do it too. It paves the way for a clean deprecation cycle now that TPROXYv4 kernels are effectively mainstream: 3.0: (2008-2010) TPROXYv2 with libcap + libcap2 3.1: (2010-2012) support TPROXYv2 + TPROXYv4 with libcap2 3.2: (2011?) support TPROXYv4 with libcap2 Amos i guess this fix went into squid 3.1.0.14 ... ? the gentoo package for that version just appeared in the portage tree and i installed it. no more warning messages in dmesg. good job! will this find it's way into squid 3.0 too ? or can i wait for 3.2 ? i did not find a planned release date. regards -alex

introduction
hi, i am interested in a patch to prevent squid from causing kernel warnings like this: warning: `squid' uses 32-bit capabilities (legacy support in use) a workaround/solution is already discussed here on the mailing list. regards -alex
Re: [PATCH] warning: `squid' uses 32-bit capabilities
actually the patch you wrote does not work for me. i tried it with squid-3.1.0.13, since the patch seemed to belong to squid-3.1, not squid-3.0. # /etc/init.d/squid start * Starting squid... 2009/10/06 00:26:05| WARNING: -D command-line option is obsolete. *** glibc detected *** /usr/sbin/squid: free(): invalid next size (fast): 0x083ec238 *** === Backtrace: = /lib/libc.so.6[0xb7c0e091] /lib/libc.so.6[0xb7c0f792] /lib/libc.so.6(cfree+0x6d)[0xb7c1284d] /usr/sbin/squid[0x818023e] === Memory map: 08048000-0825e000 r-xp 08:01 8807345/usr/sbin/squid 0825e000-08261000 r--p 00215000 08:01 8807345/usr/sbin/squid 08261000-08263000 rw-p 00218000 08:01 8807345/usr/sbin/squid 08263000-083fd000 rw-p 00:00 0 [heap] b7a0-b7a21000 rw-p 00:00 0 b7a21000-b7b0 ---p 00:00 0 b7b41000-b7b4a000 r-xp 08:01 29728532 /lib/libnss_nis-2.10.1.so b7b4a000-b7b4b000 r--p 8000 08:01 29728532 /lib/libnss_nis-2.10.1.so b7b4b000-b7b4c000 rw-p 9000 08:01 29728532 /lib/libnss_nis-2.10.1.so b7b4c000-b7b52000 r-xp 08:01 29728535 /lib/libnss_compat-2.10.1.so b7b52000-b7b53000 r--p 5000 08:01 29728535 /lib/libnss_compat-2.10.1.so b7b53000-b7b54000 rw-p 6000 08:01 29728535 /lib/libnss_compat-2.10.1.so b7b54000-b7b5e000 r-xp 08:01 29728521 /lib/libnss_files-2.10.1.so b7b5e000-b7b5f000 r--p 9000 08:01 29728521 /lib/libnss_files-2.10.1.so b7b5f000-b7b6 rw-p a000 08:01 29728521 /lib/libnss_files-2.10.1.so b7b6-b7ba3000 rw-p 00:00 0 b7ba3000-b7ce1000 r-xp 08:01 29728539 /lib/libc-2.10.1.so b7ce1000-b7ce3000 r--p 0013e000 08:01 29728539 /lib/libc-2.10.1.so b7ce3000-b7ce4000 rw-p 0014 08:01 29728539 /lib/libc-2.10.1.so b7ce4000-b7ce7000 rw-p 00:00 0 b7ce7000-b7d03000 r-xp 08:01 34303998 /usr/lib/gcc/i686-pc-linux-gnu/4.4.1/libgcc_s.so.1 b7d03000-b7d04000 r--p 0001c000 08:01 34303998 /usr/lib/gcc/i686-pc-linux-gnu/4.4.1/libgcc_s.so.1 b7d04000-b7d05000 rw-p 0001d000 08:01 34303998 /usr/lib/gcc/i686-pc-linux-gnu/4.4.1/libgcc_s.so.1 b7d05000-b7d06000 rw-p 00:00 0 b7d06000-b7d2a000 r-xp 08:01 29714603 /lib/libm-2.10.1.so b7d2a000-b7d2b000 r--p 00023000 08:01 29714603 /lib/libm-2.10.1.so b7d2b000-b7d2c000 rw-p 00024000 08:01 29714603 /lib/libm-2.10.1.so b7d2c000-b7e0f000 r-xp 08:01 34303988 /usr/lib/gcc/i686-pc-linux-gnu/4.4.1/libstdc++.so.6.0.12 b7e0f000-b7e13000 r--p 000e3000 08:01 34303988 /usr/lib/gcc/i686-pc-linux-gnu/4.4.1/libstdc++.so.6.0.12 b7e13000-b7e14000 rw-p 000e7000 08:01 34303988 /usr/lib/gcc/i686-pc-linux-gnu/4.4.1/libstdc++.so.6.0.12 b7e14000-b7e1b000 rw-p 00:00 0 b7e1b000-b7e1d000 r-xp 08:01 29714649 /lib/libdl-2.10.1.so b7e1d000-b7e1e000 r--p 1000 08:01 29714649 /lib/libdl-2.10.1.so b7e1e000-b7e1f000 rw-p 2000 08:01 29714649 /lib/libdl-2.10.1.so b7e1f000-b7e32000 r-xp 08:01 29728529 /lib/libnsl-2.10.1.so b7e32000-b7e33000 r--p 00012000 08:01 29728529 /lib/libnsl-2.10.1.so b7e33000-b7e34000 rw-p 00013000 08:01 29728529 /lib/libnsl-2.10.1.so b7e34000-b7e36000 rw-p 00:00 0 b7e36000-b7e46000 r-xp 08:01 29728517 /lib/libresolv-2.10.1.so b7e46000-b7e47000 r--p 0001 08:01 29728517 /lib/libresolv-2.10.1.so b7e47000-b7e48000 rw-p 00011000 08:01 29728517 /lib/libresolv-2.10.1.so b7e48000-b7e4b000 rw-p 00:00 0 b7e4b000-b7f82000 r-xp 08:01 60595851 /usr/lib/libcrypto.so.0.9.8 b7f82000-b7f83000 ---p 00137000 08:01 60595851 /usr/lib/libcrypto.so.0.9.8 b7f83000-b7f8b000 r--p 00137000 08:01 60595851 /usr/lib/libcrypto.so.0.9.8 b7f8b000-b7f99000 rw-p 0013f000 08:01 60595851 /usr/lib/libcrypto.so.0.9.8 b7f99000-b7f9c000 rw-p 00:00 0 b7f9c000-b7fdf000 r-xp 08:01 60600670 /usr/lib/libssl.so.0.9.8 b7fdf000-b7fe r--p 00043000 08:01 60600670 /usr/lib/libssl.so.0.9.8 b7fe-b7fe3000 rw-p 00044000 08:01 60600670 /usr/lib/libssl.so.0.9.8 b7fe3000-b7ff5000 r-xp 08:01 8396889/lib/libz.so.1.2.3 b7ff5000-b7ff6000 r--p 00011000 08:01 8396889/lib/libz.so.1.2.3 b7ff6000-b7ff7000 rw-p 00012000 08:01 8396889/lib/libz.so.1.2.3 b7ff7000-b7ff8000 r-xp 08:01 29498493 /usr/lib/libmd5.so.0.1.0 b7ff8000-b7ff9000 r--p 1000 08:01 29498493 /usr/lib/libmd5.so.0.1.0 b7ff9000-b7ffa000 rw-p 2000 08:01 29498493 /usr/lib/libmd5.so.0.1.0 b7ffa000-b8003000 r-xp 08:01 29728476 /lib/libcrypt-2.10.1.so b8003000-b8004000 r--p 8000 08:01 29728476 /lib/libcrypt-2.10.1.so
