It has long been known that the C specification of *scanf() leaves behavior undefined for things like int i; sscanf("9999999999999999", "%i", &i); C11 7.21.6.2 P12 "Matches an optionally signed integer, whose format is the same as expected for the subject sequence of the strtol function with the value 0 for the base argument." C11 7.21.6.2 P10 "If this

Hi would it be possible to consider a new parameter for replication: doveadm_local_ip which allows the source ip address to be set when connection to a remote dovecot for replication? It could be useful when the network interface has multiple ips and a specific one is used for mail services. See attached proposal. I tested against 2.2.36 only. It applies correctly against 2.3.4 with a warning,.

The context to this is that nbdkit uses sscanf to parse simple file formats in various places, eg: https://github.com/libguestfs/nbdkit/blob/b23f4f53cf71326f1dba481f64f7f182c20fa3dc/plugins/data/format.c#L171-L172 https://github.com/libguestfs/nbdkit/blob/b23f4f53cf71326f1dba481f64f7f182c20fa3dc/filters/ddrescue/ddrescue.c#L98 We can only do this safely where we can prove that overflow does not

I'm having difficulty trying to figure out how to write an R wrapper for a C function that has a "scanf-like" argument list. Recall that in C, functions like scanf() return their values through a variable number of arguments whose type and number is determined by a format string. In C this is handled by parsing the format string and then

I am trying to use dtrace to trace all sscanf calls. I am able to use pid provider for this. But my application forks off children at times to handle requests. Is there a way I can stop the child process immediately after it is started so that I can attach a pid provider to that and trace the scanf calls in it? I have tried using the "create" probe but that did not help.

The existing implementation admitted that it was not very robust in the face of garbage input (including, but not limited to, the the fact that the scanf() family has undefined behavior on integer overflow). Tighten things up by reimplementing the function. The old comment mentioned the 'human*' interface from gnulib; we can't use that for licensing reasons; so my rewrite is done

Dear list, During the last two months, I spent a lot of time trying to remove the following warnings of my package randtoolbox: congruRand.c:180:3: warning: ISO C does not support the 'I64' ms_scanf length modifier [-Wformat=] sscanf(params[0], "%" PRIu64 "\n", &inp_mod); Please see

Sharing an installed copy of dovecot between several users each running a daemon within their own account (or using the same binaries for a system daemon and a user daemon) is difficult because the compile-time directory PKG_STATEDIR (typically /var/lib/dovecot) is hard-coded as the location of things like the ssl-parameters.dat file and the replicator database. Replace all these uses of

The story of this problem, AFAIK, is that Solaris 8 YASSP and JASS and vigilant/paranoid sysadmins have been known to set a restricitve umask in /etc/default/login. OpenSSH compatibility for Solaris 8 has been spotty at times for sparcv9 targets. This time, when a sparcv9 binary tries to sscanf(3C) the numeric umask as a long octal and put it in a mode_t, SIGBUS happens. What this looks like in
