MFC r320216: Fix use-after-free introduced in r300388.

2017-06-25T17:42:27+00:00

In r300388, endnetconfig() was called on nc_handle which would release
the associated netconfig structure, which means tmpnconf->nc_netid
would be a use-after-free.

Solve this by doing endnetconfig() in return paths instead.

MFC r317660, r317710

2017-05-15T22:41:01+00:00

r317660:
Support clnt_raw's use of FD_SETSIZE as a fake file descriptor.

Accomplish this by allocating space for it in __svc_xports and allowing
it to be registered.  The failure to allocate space was causing an
out-of-bounds read in svc_getreq_common().  The failure to register
caused PR 211804.

The bug was found with CHERI bounds checking.

MFC r315162:

2017-04-07T16:08:04+00:00

libc: provide some bounds-checking through reallocarray(3).

reallocarray(3) is a non portable extension that originated in OpenBSD.
Given that it is already in FreeBSD's libc it is useful for the cases
where reallocation involves a multiplication.

MFC r303889:

2016-09-08T15:12:20+00:00

libc/rpc: replace comma with semicolon when pertinent.

Uses of commas instead of a semicolons can easily go undetected. The comma
can serve as a statement separator but this shouldn't be abused when
statements are meant to be standalone.

Use on crypto.x and rpc.x from the source tree.

This fixes the build when DESTDIR may be blank or not yet populated.
It also fixes reproducibility.

libc/rpc: Make use of some xdr_* macros. (part 2)

2016-06-09T22:18:25+00:00

xdr_rpcproc, xdr_rpcprog and xdr_rpcvers were broken in older
versions of FreeBSD but fixed in r296394.  Give them some use
hoping they help make the code somewhat more readable.
