2016-08-05sunrpc: Do not use alloca in clntudp_callWaldemar Brodkorb
CVE-2016-4429: The call is technically in a loop, and under certain circumstances (which are quite difficult to reproduce in a test case), alloca can be invoked repeatedly during a single call to clntudp_call. As a result, the available stack space can be exhausted (even though individual alloca sizes are bounded implicitly by what can fit into a UDP packet, as a side effect of the earlier successful send operation). From GNU libc: https://sourceware.org/git/gitweb.cgi?p=glibc.git;a=commit;h=bc779a1a5b3035133024b21e2f339fe4219fb11c

I mailed with Jan-Benedict Glaw, it seems VAX on Linux is really a lot of work todo and uClibc support didn't work ever.

regressions introduced in 1b3025b7352f5e432ffa1c7adc57085ac9092b77 "buildsys: switch libc to kbuild-style" unistd: Handle !UCLIBC_HAS_GET{, SUB}OPT cases libc/libc_so.a(getsubopt-susv3.os): In function getsubopt': getsubopt-susv3.c:(.text+0x0): multiple definition of getsubopt' libc/libc_so.a(getsubopt.os):getsubopt.c:(.text+0x0): first defined here. The solution is to filter out the correct files when UCLIBC_HAS_GETOPT and UCLIBC_HAS_GETSUBOPT are not defined. inet: Move INET_RPC_{DIR, OUT} before CSRC_ALL libc/libc_so.a(rpc_thread.oS): In function __rpc_thread_svc_max_pollfd': rpc_thread.c:(.text+0x148): undefined reference to svc_max_pollfd' libc/libc_so.a(rpc_thread.oS): In function __rpc_thread_svc_pollfd': rpc_thread.c:(.text+0x184): undefined reference to svc_pollfd' The CSRC_ALL variable uses the INET_RPC_DIR variable which is initialized later on.

2012-03-26inet:rpc: fix build in !NPTL caseCarmelo Amoroso
__libc_once is not available / needed when multithreading support is not enabled, so authnone_create() calls authnone_create_once() directly. When LT.{old,new} is used instead of NPTL, it needs to explicitly include <bits/libc-lock.h> to get __libc_once to be visible. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

2010-07-27new helper funcs for alloca/malloc with mmu/nommuMike Frysinger
The rpc rcmd code has some ugly ifdef mazes to handle mmu/nommu differences just to select alloca or malloc. Unify those with some helper macros in a new header, and then convert the rcmd code over to it. This is all geared towards fixing the getdents helper functions which only use alloca() atm. Now that we have helper functions, convert the getdents functions over too. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Steven J. Magnani <steve@digidescorp.com>
