* [ipv4] Rewrite inet_aton()Michael Brown2015-02-191-0/+2
| | | | | | | | | | The implementation of inet_aton() has an unknown provenance. Rewrite this code to avoid potential licensing uncertainty. Also move the code from core/misc.c to its logical home in net/ipv4.c, and add a few extra test cases. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [crypto] Fix parsing of OCSP responder ID key hashMichael Brown2014-11-241-0/+411
| | | | | | | | | | | | | | | | | | | | We currently compare the entirety of the KeyHash object (including the ASN.1 tag and length byte) against the raw SHA-1 hash of the certificate's public key. This causes OCSP validation to fail for any responses which identify the responder by key hash rather than by name, and hence prevents the use of X.509 certificates where any certificate in the chain has an OCSP responder which chooses to identify itself via its key hash. Fix by adding the missing asn1_enter() required to enter the ASN.1 octet string containing the key hash. Also add a corresponding test case including an OCSP response where the responder is identified by key hash, to ensure that this functionality cannot be broken in future.

* [libc] Prevent strndup() from reading beyond the end of the stringMichael Brown2014-05-181-0/+20
| | | | | | | | | | | | strndup() may be called on a string which is not NUL-terminated. Use strnlen() instead of strlen() to ensure that we do not read beyond the end of such a string. Add self-tests for strndup(), including a test case with an unterminated string. Originally-fixed-by: Marin Hannache <git@mareo.fr> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [test] Check for correct -mrtd assumption on libgcc arithmetic functionsMichael Brown2014-04-261-4/+74
| | | | | | | | | | | | | | | | | | | | | | | | As observed in commit 082cedb ("[build] Fix __libgcc attribute for recent gcc versions"), recent versions of gcc have changed the semantics of -mrtd as applied to the implicit arithmetic functions. It is possible for tests to succeed even if our assumptions about gcc's interpretation of -mrtd are incorrect. In particular, if gcc chooses to utilise a frame pointer in the calling function, then it can tolerate a temporarily incorrect stack pointer (since the stack pointer will shortly afterwards be restored from the frame pointer anyway). Add tests designed specifically to check that our implementations of the implicit arithmetic functions manipulate the stack pointer as expected by gcc. The effect of these tests can be observed by temporarily reverting commit 082cedb ("[build] Fix __libgcc attribute for recent gcc versions"): without this fix in place, the tests will fail on gcc 4.7 and later.

* [test] Add tests for 64-bit divisionMichael Brown2014-04-251-0/+122
| | | | | | | | | | On a 32-bit system, 64-bit division is implemented using the libgcc functions provided in __udivmoddi4.c etc. Calls to these functions are generated automatically by gcc, with a calling convention that is somewhat empirical in nature. Add these self-tests primarily as a check that we are using the correct calling convention. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [crypto] Generalise X.509 cache to a full certificate storeMichael Brown2014-03-282-37/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Expand the concept of the X.509 cache to provide the functionality of a certificate store. Certificates in the store will be automatically used to complete certificate chains where applicable. The certificate store may be prepopulated at build time using the CERT=... build command line option. For example: make bin/ipxe.usb CERT=mycert1.crt,mycert2.crt Certificates within the certificate store are not implicitly trusted; the trust list is specified using TRUST=... as before. For example: make bin/ipxe.usb CERT=root.crt TRUST=root.crt This can be used to embed the full trusted root certificate within the iPXE binary, which is potentially useful in an HTTPS-only environment in which there is no HTTP server from which to automatically download cross-signed certificates or other certificate chain fragments. This usage of CERT= extends the existing use of CERT= to specify the client certificate. The client certificate is now identified automatically by checking for a match against the private key. For example: make bin/ipxe.usb CERT=root.crt,client.crt TRUST=root.crt KEY=client.key Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [uri] Refactor URI parsing and formattingMichael Brown2014-02-272-120/+833
| | | | | | | | | | | | | | | | | | | | | | | | Add support for parsing of URIs containing literal IPv6 addresses (e.g. "http://[fe80::69ff:fe50:5845%25net0]/boot.ipxe"). Duplicate URIs by directly copying the relevant fields, rather than by formatting and reparsing a URI string. This relaxes the requirements on the URI formatting code and allows it to focus on generating human-readable URIs (e.g. by not escaping ':' characters within literal IPv6 addresses). As a side-effect, this allows relative URIs containing parameter lists (e.g. "../boot.php##params") to function as expected. Add validity check for FTP paths to ensure that only printable characters are accepted (since FTP is a human-readable line-based protocol with no support for character escaping). Construct TFTP next-server+filename URIs directly, rather than parsing a constructed "tftp://..." string, Add self-tests for URI functions. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [settings] Remove "uristring" setting typeMichael Brown2014-02-271-13/+0Star
| | | | | | | | | | | | | | Commit b5f5f73 ("[cmdline] Expand settings within each command-line token individually") effectively rendered the "uristring" setting type obsolete, since strings containing whitespace no longer break the command line parser. The concept of the "uristring" type is not well defined, since URI escaping rules depend on which portion of a URI is being escaped. Remove the "uristring" type, converting it into an alias for the "string" setting type so as to avoid breaking existing scripts. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [dns] Support DNS search listsMichael Brown2014-02-052-0/+606
| | | | | | | | | | | Update the DNS resolver to support DNS search lists (as provided by DHCP option 119, DHCPv6 option 24, or NDP option 31). Add validation code to ensure that parsing of DNS packets does not overrun the input, get stuck in infinite loops, or (worse) write beyond the end of allocated buffers.

| | | | | | | | | | The fetch_setting() family of functions may currently modify the definition of the specified setting (e.g. to add missing type information).

* [ipv6] Replace IPv6 stackMichael Brown2013-09-032-0/+116
| | | | | | | | | | | | | | | | Replace the existing partially-implemented IPv6 stack with a fresh implementation. This implementation is not yet complete. The IPv6 transmit and receive datapaths are functional (including fragment reassembly and parsing of arbitrary extension headers). NDP neighbour solicitations and advertisements are supported. ICMPv6 echo is supported. At present, only link-local addresses may be used, and there is no way to specify an IPv6 address as part of a URI (either directly or via a DNS lookup).
