2012-10-05cleanup useless return sentenceAmos Kong
This patch cleans up return sentences in the end of void functions. Reported-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Amos Kong <akong@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@gmail.com>
2011-09-28slirp: Fix use after release on tcp_inputJan Kiszka
ti points into the m buffer. But the latter may already be released right after the dodata: label. Move the test before the potential release. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2011-09-20Merge remote-tracking branch 'kiszka/queues/slirp' into stagingAnthony Liguori
2011-09-16Remove blanks before \n in output stringsStefan Weil
Those blanks violate the coding conventions, see scripts/checkpatch.pl. Blanks missing after colons in the changed lines were added. This patch does not try to fix tabs, long lines and other problems in the changed lines, therefore checkpatch.pl reports many violations.

2011-09-16slirp: Fill TCP/IP header template after SYN receptionJan Kiszka
This ensures we can cleanly signal the drop in case the connection timer fires. So far we sent those frames to nowhere (target IP 0.0.0.0). Found by the new assertion on invalid IPs in arp_table_search. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
2011-07-23slirp: Replace m_freem with m_freeJan Kiszka
Remove this pointless wrapping. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-07-25slirp: Replace u_int8_t, u_int16_t, u_int32_t, u_int64_t by standard int typesStefan Weil
There is no need to have a second set of integral types. Replace them by the standard types from stdint.h. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-06-29slirp: Factor out internal state structureJan Kiszka
The essence of this patch is to stuff (almost) all global variables of the slirp stack into the structure Slirp. In this step, we still keep the structure as global variable, directly accessible by the whole stack. Changes to the external interface of slirp will be applied in the following patches.

2009-06-29slirp: Drop statistic codeJan Kiszka
As agreed on the mailing list, there is no interest in keeping the usually disabled slirp statistics in the tree. So this patch removes them. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29slirp: Drop dead codeJan Kiszka
After all its years inside the qemu tree, there is no point in keeping the dead code paths of slirp. This patch is a first round of removing usually commented out code parts. More cleanups need to follow (and maybe finally a proper reindention). Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29slirp: Prepare for persistent socket state flagsJan Kiszka
This prepares for adding flags to socket.so_state that must not be removed during the lifetime of a socket. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29slirp: Rework internal configurationJan Kiszka
The user mode IP stack is currently only minimally configurable /wrt to its virtual IP addresses. This is unfortunate if some guest has a fixed idea of which IP addresses to use. Therefore this patch prepares the stack for fully configurable IP addresses and masks. The user interface and default addresses remain untouched in this step, they will be enhanced in the following patch.

2009-01-26Remove the advertising clause from the slirp licensealiguori
According to the FSF, the 4-clause BSD license, which slirp is covered under, is not compatible with the GPL or LGPL[1]. [1] http://www.fsf.org/licensing/licenses/index_html#GPLIncompatibleLicenses There are three declared copyright holders in slirp that use the 4-clause BSD license, the Regents of UC Berkley, Danny Gasparovski, and Kelly Price. Below are the appropriate permissions to remove the advertise clause from slirp from each party. Special thanks go to Richard Fontana from Red Hat for contacting all of the necessary authors to resolve this issue! Regents of UC Berkley: From ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change July 22, 1999 To All Licensees, Distributors of Any Version of BSD: As you know, certain of the Berkeley Software Distribution ("BSD") source code files require that further distributions of products containing all or portions of the software, acknowledge within their advertising materials that such products contain software developed by UC Berkeley and its contributors. Specifically, the provision reads: " * 3. All advertising materials mentioning features or use of this software * must display the following acknowledgement: * This product includes software developed by the University of * California, Berkeley and its contributors." Effective immediately, licensees and distributors are no longer required to include the acknowledgement within advertising materials. Accordingly, the foregoing paragraph of those BSD Unix files containing it is hereby deleted in its entirety. William Hoskins Director, Office of Technology Licensing University of California, Berkeley Danny Gasparovski: Subject: RE: Slirp license Date: Thu, 8 Jan 2009 10:51:00 +1100 From: "Gasparovski, Daniel" <Daniel.Gasparovski@ato.gov.au> To: "Richard Fontana" <rfontana@redhat.com> Hi Richard, I have no objection to having Slirp code in QEMU be licensed under the 3-clause BSD license. Thanks for taking the effort to consult me about this. Dan ... Kelly Price: Date: Thu, 8 Jan 2009 19:38:56 -0500 From: "Kelly Price" <strredwolf@gmail.com> To: "Richard Fontana" <rfontana@redhat.com> Subject: Re: Slirp license Thanks for contacting me, Richard. I'm glad you were able to find Dan, as I've been "keeping the light on" for Slirp. I have no use for it now, and I have little time for it (now holding onto Keenspot's Comic Genesis and having a regular US state government position). If Dan would like to return to the project, I'd love to give it back to him. As for copyright, I don't own all of it. Dan does, so I will defer to him. Any of my patches I will gladly license to the 3-part BSD license. My interest in re-licensing was because we didn't have ready info to contact Dan. If Dan would like to port Slirp back out of QEMU, a lot of us 64-bit users would be grateful. Feel free to share this email address with Dan. I will be glad to effect a transfer of the project to him and Mr. Bellard of the QEMU project.
