Subject: [PATCH] Add a safety timeout to epoll
Add a safety timeout just in case something goes wrong with the use of

From d284ec7dc9fe0a824b177873078aeb36a25b7878 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Always choose highest requested debug level
Allowing the CLI to lower the debug level specified in a config file
is dubious, and previously broken since we don't distinguish "default
value" from "explicitly requested value of 0" in popt. This resulted
in "Debug Enabled (level: 0)" even when the log level was not actually
0, which is confusing for users.
Remove the gp_debug_args() function since it is no longer used.

From 51bba6bf325716534c509e0528d2ccfd0050d28c Mon Sep 17 00:00:00 2001
From: Simo Sorce <simo@redhat.com>
Date: Wed, 17 Apr 2019 18:00:59 -0400
Subject: [PATCH] Change the way we handle encrypted buffers
The previous change has backwards incompatible behavior that may also
lead to buffer overruns.
Because we have no easy way to indicate a format change and to maintain
backwards compatibility for the ciphers that were working (those that
added padding were hopelessly borken anyway) introduce code to simply
add padding that we can recognize and remove when we read back the token.
On ciphers that do not add padding this is basically a no op and the
tokens will be identical to the ones we previously emitted.
On ciphers that add padding we pad the plaintext so that we hit a block
boundary and cause no extra padding to be added by krb5_c_encrypt
itself. On decryption we check if padding bytes are appended to the
buffer and remove them.

Subject: [PATCH] Include length when using krb5_c_decrypt()
For some enctypes, krb5_c_decrypt() will add padding bytes which are
included in the returned length. However, functions which use the
objects we're storing aren't always prepared for that: in particular,
gss_import_cred() will declare a token invalid if there's trailing
garbage.
Work around this by including 4 bytes of length on encrypted objects.
