AC_PREREQ([2.60])
Avoid buffer overflow in RC4 loop comparison (#336) The rc4 function iterates over a buffer of size buffer_len who's maximum value is INT_MAX with a counter of type short that is not guaranteed to have maximum size INT_MAX. In circumstances where short is narrower than int and where buffer_len is larger than the maximum value of a short, it may be possible to loop infinitely as counter will overflow and never be greater than or equal to buffer_len. The solution is to make the comparison be between types of equal width. This commit defines counter as an int. Fix By: Fionn Fitzmaurice (@fionn)

CARES_VERSION_INFO="12:0:10"
attempt to fix 1.17.0 release distribution issues
4 years ago
dnl This flag accepts an argument of the form current[:revision[:age]]. So,
dnl passing -version-info 3:12:1 sets current to 3, revision to 12, and age to
dnl 1.
dnl
dnl If either revision or age are omitted, they default to 0. Also note that age
dnl must be less than or equal to the current interface number.
dnl
dnl Here are a set of rules to help you update your library version information:
dnl
dnl 1.Start with version information of 0:0:0 for each libtool library.
dnl
dnl 2.Update the version information only immediately before a public release of
dnl your software. More frequent updates are unnecessary, and only guarantee
dnl that the current interface number gets larger faster.
dnl
dnl 3.If the library source code has changed at all since the last update, then
dnl increment revision (c:r+1:a)
dnl
dnl 4.If any interfaces have been added, removed, or changed since the last
dnl update, increment current, and set revision to 0. (c+1:r=0:a)
dnl
dnl 5.If any interfaces have been added since the last public release, then
dnl increment age. (c:r:a+1)
dnl
dnl 6.If any interfaces have been removed since the last public release, then
dnl set age to 0. (c:r:a=0)

Reorganize source tree (#349) Originally started by Daniel Stenberg (@bagder) with #123, this patch reorganizes the c-ares source tree to have a more modern layout. It also fixes out of tree builds for autotools, and automatically builds the tests if tests are enabled. All tests are passing which tests each of the supported build systems (autotools, cmake, nmake, mingw gmake).

# Due to libtool and automake machinery limitations of not allowing
# specifying separate CPPFLAGS or CFLAGS when compiling objects for
# inclusion of these in shared or static libraries, we are forced to
# build using separate configure runs for shared and static libraries
# on systems where different CPPFLAGS or CFLAGS are mandatory in order
# to compile objects for each kind of library. Notice that relying on
# the '-DPIC' CFLAG that libtool provides is not valid given that the
# user might for example choose to build static libraries with PIC.
#
#
# Make our Makefile.am files use the staticlib CPPFLAG only when strictly
# targeting a static library and not building its shared counterpart.

Support ipv6 link-local servers and %iface syntax (#646) Some environments may send router advertisements on a link setting their link-local (fe80::/10) address as a valid DNS server to the remote system. This will cause a DNS entry to be created like `fe80::1%iface`, since all link-local network interfaces are technically part of the same /10 subnet, it must be told what interface to send packets through explicitly if there are multiple physical interfaces. This PR adds support for the %iface modifier when setting DNS servers via `/etc/resolv.conf` as well as via `ares_set_servers_csv()`. For MacOS and iOS it is assumed that libresolve will set the `sin6_scope_id` and should be supported, but my test systems don't seem to read the Router Advertisement for RDNSS link-local. Specifying the link-local dns server on MacOS via adig has been tested and confirmed working. For Windows, this is similar to MacOS in that the system doesn't seem to honor the RDNSS RA, but specifying manually has been tested to work. At this point, Android support does not exist.

Replace hosts parser, add caching capabilities (#591) HOSTS FILE PROCESSING OVERVIEW ============================== The hosts file on the system contains static entries to be processed locally rather than querying the nameserver. Each row is an IP address followed by a list of space delimited hostnames that match the ip address. This is used for both forward and reverse lookups. We are caching the entire parsed hosts file for performance reasons. Some files may be quite sizable and as per Issue #458 can approach 1/2MB in size, and the parse overhead on a rapid succession of queries can be quite large. The entries are stored in forwards and backwards hashtables so we can get O(1) performance on lookup. The file is cached until the file modification timestamp changes (or 60s if there is no implemented stat() capability). The hosts file processing is quite unique. It has to merge all related hosts and ips into a single entry due to file formatting requirements. For instance take the below: ``` 127.0.0.1 localhost.localdomain localhost ::1 localhost.localdomain localhost 192.168.1.1 host.example.com host 192.168.1.5 host.example.com host 2620:1234::1 host.example.com host6.example.com host6 host ``` This will yield 2 entries. 1) ips: `127.0.0.1,::1` hosts: `localhost.localdomain,localhost` 2) ips: `192.168.1.1,192.168.1.5,2620:1234::1` hosts: `host.example.com,host,host6.example.com,host6` It could be argued that if searching for `192.168.1.1` that the `host6` hostnames should not be returned, but this implementation will return them since they are related (both ips have the fqdn of host.example.com). It is unlikely this will matter in the real world. Fix By: Brad House (@bradh352)

CARES_CHECK_FUNC_STAT
Support ipv6 link-local servers and %iface syntax (#646) Some environments may send router advertisements on a link setting their link-local (fe80::/10) address as a valid DNS server to the remote system. This will cause a DNS entry to be created like `fe80::1%iface`, since all link-local network interfaces are technically part of the same /10 subnet, it must be told what interface to send packets through explicitly if there are multiple physical interfaces. This PR adds support for the %iface modifier when setting DNS servers via `/etc/resolv.conf` as well as via `ares_set_servers_csv()`. For MacOS and iOS it is assumed that libresolve will set the `sin6_scope_id` and should be supported, but my test systems don't seem to read the Router Advertisement for RDNSS link-local. Specifying the link-local dns server on MacOS via adig has been tested and confirmed working. For Windows, this is similar to MacOS in that the system doesn't seem to honor the RDNSS RA, but specifying manually has been tested to work. At this point, Android support does not exist.

In circumstances where short is narrower than int and where buffer_len is larger than the maximum value of a short, it may be possible to loop infinitely as counter will overflow and never be greater than or equal to buffer_len.

Reorganize source tree (#349) Originally started by Daniel Stenberg (@bagder) with #123, this patch reorganizes the c-ares source tree to have a more modern layout. It also fixes out of tree builds for autotools, and automatically builds the tests if tests are enabled. All tests are passing which tests each of the supported build systems (autotools, cmake, nmake, mingw gmake). There may be some edge cases that will have to be caught later on for things I'm not aware of. Fix By: Brad House (@bradh352)

Avoid buffer overflow in RC4 loop comparison (#336) The rc4 function iterates over a buffer of size buffer_len who's maximum value is INT_MAX with a counter of type short that is not guaranteed to have maximum size INT_MAX. In circumstances where short is narrower than int and where buffer_len is larger than the maximum value of a short, it may be possible to loop infinitely as counter will overflow and never be greater than or equal to buffer_len. The solution is to make the comparison be between types of equal width. This commit defines counter as an int. Fix By: Fionn Fitzmaurice (@fionn)
