The following build error occurred during an alpha build: net/core/sock.c:274:36: error: initializer element is not constant Dave Anglin says: > Here is the line in sock.i: > > struct static_key memalloc_socks = ((struct static_key) { .enabled = > ((atomic_t) { (0) }) }); The above line contains two compound literals. It also uses a designated initializer to initialize the field enabled. A compound literal is not a constant expression. The location of the above statement isn't fully clear, but if a compound literal occurs outside the body of a function, the initializer list must consist of constant expressions.

Similar to x86/sparc/powerpc implementations except: 1) we implement an extremely efficient has_zero()/find_zero() sequence with both prep_zero_mask() and create_zero_mask() no-operations. 2) Our output from prep_zero_mask() differs in that only the lowest eight bits are used to represent the zero bytes nevertheless it can be safely ORed with other similar masks from prep_zero_mask() and forms input to create_zero_mask(), the two fundamental properties prep_zero_mask() must satisfy. Tests on EV67 and EV68 CPUs revealed that the generic code is essentially as fast (to within 0.5% of CPU cycles) of the old Alpha specific code for large quadword-aligned strings, despite the 30% extra CPU instructions executed. In contrast, the generic code for unaligned strings is substantially slower (by more than a factor of 3) than the old Alpha specific code.

Currently we export SOCK_NONBLOCK to user space but that conflicts with the definition from glibc leading to compilation errors in user programs (e.g. see Debian bug #658460).

Some of the arguments to {g,s}etsockopt are passed in userland pointers. If we try to use the 64bit entry point, we end up sometimes failing. For example, dhcpcd doesn't run in x32: # dhcpcd eth0 dhcpcd[1979]: version 5.5.6 starting dhcpcd[1979]: eth0: broadcasting for a lease dhcpcd[1979]: eth0: open_socket: Invalid argument dhcpcd[1979]: eth0: send_raw_packet: Bad file descriptor The code in particular is getting back EINVAL when doing: struct sock_fprog pf; setsockopt(s, SOL_SOCKET, SO_ATTACH_FILTER, &pf, sizeof(pf)); Diving into the kernel code, we can see: include/linux/filter.h: struct sock_fprog { unsigned short len; struct sock_filter __user *filter; }; net/core/sock.c: case SO_ATTACH_FILTER: ret = -EINVAL; if (optlen == sizeof(struct sock_fprog)) { struct sock_fprog fprog; ret = -EFAULT; if (copy_from_user(&fprog, optval, sizeof(fprog))) break; ret = sk_attach_filter(&fprog, sk); } break; arch/x86/syscalls/syscall_64.tbl: 54 common setsockopt sys_setsockopt 55 common getsockopt sys_getsockopt So for x64, sizeof(sock_fprog) is 16 bytes. For x86/x32, it's 8 bytes. This comes down to the pointer being 32bit for x32, which means we need to do structure size translation. But since x32 comes in directly to sys_setsockopt, it doesn't get translated like x86. After changing the syscall table and rebuilding glibc with the new kernel headers, dhcp runs fine in an x32 userland. Oddly, it seems like Linus noted the same thing during the initial port, but I guess that was missed/lost along the way: https://lkml.org/lkml/2011/8/26/452 [ hpa: tagging for -stable since this is an ABI fix. ] Bugzilla: https://bugs.gentoo.org/423649Reported-by: NMads <mads@ab3.no> Signed-off-by: NMike Frysinger <vapier@gentoo.org> Link: http://lkml.kernel.org/r/1345320697-15713-1-git-send-email-vapier@gentoo.org Cc: H.

-
由 NeilBrown 提交于
A 'struct r10bio' has an array of per-copy information at the end. This array is declared with size [0] and r10bio_pool_alloc allocates enough extra space to store the per-copy information depending on the number of copies needed. So declaring a 'struct r10bio on the stack isn't going to work. It won't allocate enough space, and memory corruption will ensue. So in the two places where this is done, declare a sufficiently large structure and use that instead. The two call-sites of this bug were introduced in 3.4 and 3.5 so this is suitable for both those kernels. The patch will have to be modified for 3.4 as it only has one bug.

This callback is a no-op in nouveau, and the upcoming apple-gmux switcheroo support won't require it either. Rather than forcing drivers to stub it out, just make it optional and remove the callback from nouveau.

vga_switcheroo assumes that the handler will be registered before the last client, otherwise switching will not be enabled. Likewise it's assumed that the handler will not be unregistered without at least one client also being unregistered, otherwise switching will remain enabled despite no longer having a handler. These assumptions cannot be enforced if the handler is in a separate driver from both clients, as with the gmux found in Apple laptops. Remove this assumption.
