I suspect that the driver hasn't been tested with RT_BIG_ENDIAN (in fact it hadn't even been compiled, since one of the structures was missing a ;) but it's too big a mess for me to follow. Maybe I should ask on the linux-wireless list? Bye -- Luca ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel

This is the patch out of the series, which got committed to trunk lately, which
is appropriate for Barrier Breaker.

[OpenWrt-Devel] [PATCH][RESEND.3] ar71xx:stops qihoo c301 booting into backup firmware
Openwrt recently adds Qihoo [NYSE:QIHU] C301 router support.
However, this router has a backup firmware in the second flash and the
current trunk can only boot 3 times before u-boot boots into that backup
firmware. This is a stratgy for unbricking.
This patch makes u-boot happy.

Routers (to which I have some experience at), rarely have processes running that wouldn't matter if they are randomly killed; on a desktop system you immediately notice an issue, and you can reboot, a router is typically running unattended. Being locked out of such a system because another process had a memory leak, can be an issue. Turning off overcommit so that a program that wants to spawn a child will end up requiring double it's memory (for the time between the fork and the exec) is likely to cause programs to fail when they don't need to. I'd be surprised if fork and exec worked that way. After a fork the two processes share the same physical pages (see the notes on fork() manpage), and overcommit applies to physical ram, not virtual. No, Overcommit says that you can have more virtual RAM than physical RAM + swap. That's what overcommit is. So when you fork a process, it takes double the memory with overcommit off than it does with overcommit on. And unlike desktops, you can't just say "allocate a lot of swap" to cover this up. The same argument works the other way as well. A process using more memory than the available in the router will force some other (arbitrary) process to be killed. Unlike desktops you can't just say "allocate a lot of swap" to cover this up. What you _can_ do, is tell to the process that uses more memory than the existing one, that there is no memory left. But turning overcommit off doesn't tell a process that uses more memory than the existing one that there is no memory left, it tells the first process that tries to allocate memory after it runs out that there is no memory left. This could be the process that's using an unusual amount of memory, or it could be sshd allocating a buffer to use to log. Even if it gets the right process, you are assuming that the programs properly check for errors after anything that allocates memory. This is very commonly not the case, so you still get random failures.
