svn commit: r315956 - in head/sys: netinet netinet6
Author: karels Date: Sat Mar 25 15:06:28 2017 New Revision: 315956 URL: https://svnweb.freebsd.org/changeset/base/315956 Log: Fix reference count leak with L2 caching. ip_forward, TCP/IPv6, and probably SCTP leaked references to L2 cache entry because they used their own routes on the stack, not in_pcb routes. The original model for route caching was callers that provided a route structure to ip{,6}input() would keep the route, and this model was used for L2 caching as well. Instead, change L2 caching to be done by default only when using a route structure in the in_pcb; the pcb deallocation code frees L2 as well as L3 cacches. A separate change will add route caching to TCP/IPv6. Another suggestion was to have the transport protocols indicate willingness to use L2 caching, but this approach keeps the changes in the network level Reviewed by:ae gnn MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D10059 and those below, will be ignored-- > Description of fields to fill in above: 76 columns --| > PR: If and which Problem Report is related. > Submitted by: If someone else sent in the change. > Reported by: If someone else reported the issue. > Reviewed by: If someone else reviewed your modification. > Approved by: If you needed approval for this commit. > Obtained from:If the change is from a third party. > MFC after:N [day[s]|week[s]|month[s]].

svn commit: r340474 - head/sys/net/altq
Author: karels Date: Fri Nov 16 03:42:29 2018 New Revision: 340474 URL: https://svnweb.freebsd.org/changeset/base/340474 Log: Fix flags collision causing inability to enable CBQ in ALTQ The CBQ BORROW flag conflicts with the RMCF_CODEL flag; the two sets of definitions actually define the same things. The symptom is that a kernel with CBQ support and not CODEL fails to load a QoS policy with the obscure error "pfctl: DIOCADDALTQ: Cannot allocate memory." If ALTQ_DEBUG is enabled, the error becomes a little clearer: "rmc_newclass: CODEL not configured for CBQ!" is printed by the kernel. There really shouldn't be two sets of macros that have to be defined consistently, but the include structure isn't right for exporting CBQ flags to altq_rmclass.h. Re-align the definitions, and add CTASSERTs in the kernel to ensure that the definitions are consistent.

ps output line length (was: svn commit: r314685 - head/bin/ps)

I agree with his rational, and disagree with the change. It seems to me that the consensus was that the change was incorrect, although that might just be my opinion. However, I really think that the change needs to be reverted. The rationale for the original code was that, for interactive uses, the output line length should be the same for "ps ...", "ps ...|more", and "ps ... |grep". The -w option exists to make the line longer; there is no option to use the terminal size even if the output is redirected. Hence, the tests for stderr or stdin being a tty. This behavior has been in place since 1990, as noted, and no substantial rationale has been given for changing it other than "it doesn't matter if you use less with side-to-side scrolling." fwiw, I'm sure I discussed that code with Marc at the time. As was stated, scripts that want to use the full line should use -ww. Interactive users have long been used to using -w when they need longer output lines, e.g. to match patterns that don't occur within a screen's width. I propose reverting this change.

Followups to arch@, please.] [Sorry if this topic has been covered before; just let me know. Neither my freebsd.org or Google searches located anything, although I didn't try all that hard.] I am astounded to hear that the btoc() macro still lives on, along with ctob() (bytes to clicks, and clicks to bytes). They don't seem to have suitable MI replacements (at least not in ). For those who don't know/remember: these macros were used to convert physical addresses to values for the segment base registers (PARs) on the PDP-11, where there was no actual "page size" analogous to newer hardware. (A click, the 'c' in btoc/ctob, was 64 bytes, the unit of scaling to keep physical addresses in the hardware registers fitting in 16 bits.) Since then, the macros hav= e been subverted to operate in pages, starting with the VAX in 32/V, rather than coming up with a new, more appropriate name. I am wondering whether it is finally time to deprecate PDP-11-based nomenclature. Clicks have not been a "thing" for many years; but pages are nearly universal (modulo superpages, etc). I see that many architectures have architecture-dependent xxx_btop() and xxx_ptob() macros, which are similar but annoyingly different in details like casts. Unlike btoc(), the xxx_btop() versions do not round. I wonde= r, though, whether it is time to hoist *_btop/*_ptob into a new architecture- independent replacement for btoc/ctob. btop() and ptob() come to mind, although I don't know what Linux (etc) does along these lines. I see just over 100 uses of btoc()/ctob() overall, but of course we would need to keep deprecated versions for a while. Thoughts on changing the KPI here? We'd have to agree on details like rounding and casting, but my first reaction would be no to both.

svn commit: r341737 - stable/12/sys/net/altq
Author: karels Date: Sat Dec 8 14:54:33 2018 New Revision: 341737 URL: https://svnweb.freebsd.org/changeset/base/341737 Log: MFC r340474: Fix flags collision causing inability to enable CBQ in ALTQ The CBQ BORROW flag conflicts with the RMCF_CODEL flag; the two sets of definitions actually define the same things. The symptom is that a kernel with CBQ support and not CODEL fails to load a QoS policy with the obscure error "pfctl: DIOCADDALTQ: Cannot allocate memory." If ALTQ_DEBUG is enabled, the error becomes a little clearer: "rmc_newclass: CODEL not configured for CBQ!" is printed by the kernel. There really shouldn't be two sets of macros that have to be defined consistently, but the include structure isn't right for exporting CBQ flags to altq_rmclass.h. Re-align the definitions, and add CTASSERTs in the kernel to ensure that the definitions are consistent.

svn commit: r362353 - in head/sys: arm64/broadcom/genet dev/mii
Author: karels Date: Thu Jun 18 23:57:10 2020 New Revision: 362353 URL: https://svnweb.freebsd.org/changeset/base/362353 Log: Add support for bcm54213PE in brgphy. This chip is used in the Rasperry Pi 4, and is supported by the if_genet driver. Currently we use the ukphy mii driver, this patch switches over to the brgphy mii driver instead. To support the rgmii-rxid phy mode, which is now the default in the Linux dtb, we add support for clock skewing. These changes are taken from OpenBSD and NetBSD, except for the bailout in brgphy_bcm54xx_clock_delay() in rgmii mode, which was found necessary after testing.

MFC r315956 ip_forward, TCP/IPv6, and probably SCTP leaked references to L2 cache entry because they used their own routes on the stack, not in_pcb routes. The original model for route caching was callers that provided a route structure to ip{,6}input() would keep the route, and this model was used for L2 caching as well. Instead, change L2 caching to be done by default only when using a route structure in the in_pcb; the pcb deallocation code frees L2 as well as L3 cacches. A separate change will add route caching to TCP/IPv6. Another suggestion was to have the transport protocols indicate willingness to use L2 caching, but this approach keeps the changes in the network level Reviewed by:ae gnn MFC after: 2 weeks Differential Revision: https://reviews.freebsd.org/D10059 Modified: stable/11/sys/netinet/in_pcb.c stable/11/sys/netinet/ip_output.c stable/11/sys/netinet6/ip6_output.c Directory Properties: stable/11/ (props changed) Modified: stable/11/sys/netinet/in_pcb.c == --- stable/11/sys/netinet/in_pcb.c Sun Apr 9 21:50:21 2017 (r316667) +++ stable/11/sys/netinet/in_pcb.c Mon Apr 10 01:26:12 2017 (r316668) @@ -326,6 +326,12 @@ in_pcballoc(struct socket *so, struct in #endif inp->inp_gencnt = ++pcbinfo->ipi_gencnt; refcount_init(&inp->inp_refcount, 1); /* Reference from inpcbinfo */ + + /* +* Routes in inpcb's can cache L2 as well; they are guaranteed +* to be cleaned up. +*/ + inp->inp_route.ro_flags = RT_LLE_CACHE; INP_LIST_WUNLOCK(pcbinfo); #if defined(IPSEC) || defined(IPSEC_SUPPORT) || defined(MAC) out: Modified: stable/11/sys/netinet/ip_output.c == --- stable/11/sys/netinet/ip_output.c Sun Apr 9 21:50:21 2017 (r316667) +++ stable/11/sys/netinet/ip_output.c Mon Apr 10 01:26:12 2017 (r316668) @@ -241,8 +241,7 @@ ip_output(struct mbuf *m, struct mbuf *o if (ro == NULL) { ro = &iproute; bzero(ro, sizeof (*ro)); - } else - ro->ro_flags |= RT_LLE_CACHE; + } #ifdef FLOWTABLE if (ro->ro_rt == NULL) Modified: stable/11/sys/netinet6/ip6_output.c == --- stable/11/sys/netinet6/ip6_output.c Sun Apr 9 21:50:21 2017 (r316667) +++ stable/11/sys/netinet6/ip6_output.c Mon Apr 10 01:26:12 2017 (r316668) @@ -493,8 +493,7 @@ ip6_output(struct mbuf *m0, struct ip6_p if (ro == NULL) { ro = &ip6route; bzero((caddr_t)ro, sizeof(*ro)); - } else - ro->ro_flags |= RT_LLE_CACHE; + } ro_pmtu = ro; if (opt && opt->ip6po_rthdr) ro = &opt->ip6po_route; ___ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"

I'm with Warner on this. I saw a lot to dislike in the changes, and very little actual improvement. If we were starting from scratch, I might be willing to accept the changes to have a formatter (albeit begrudingly), but we are not starting from scratch. The churn would be horrible, and the benefit very little in comparison. Interesting experiment, but let's keep it just an experiment.

Fix address annotation in xml output from w The libxo xml feature of adding an annotation with the "original" address from the utmpx file if it is different than the final "from" field was broken by r351379.
