82ad601a05Sjv * S10_FEATURE_IS_PRESENT is a macro that helps facilitate conditional
83ad601a05Sjv * emulation. For each constant N defined in the s10_emulated_features
84ad601a05Sjv * enumeration in usr/src/uts/common/brand/solaris10/s10_brand.h,
85ad601a05Sjv * S10_FEATURE_IS_PRESENT(N) is true iff the feature/backport represented by N
86ad601a05Sjv * is present in the Solaris 10 image hosted within the zone. In other words,
87ad601a05Sjv * S10_FEATURE_IS_PRESENT(N) is true iff the file /usr/lib/brand/solaris10/M,
88ad601a05Sjv * where M is the enum value of N, was present in the zone when the zone booted.
89ad601a05Sjv *
90ad601a05Sjv *
91ad601a05Sjv * *** Sample Usage
92ad601a05Sjv *
93ad601a05Sjv * Suppose that you need to backport a fix to Solaris 10 and there is
94ad601a05Sjv * emulation in place for the fix. Suppose further that the emulation won't be
95ad601a05Sjv * needed if the fix is backported (i.e., if the fix is present in the hosted
96ad601a05Sjv * Solaris 10 environment, then the brand won't need the emulation). Then if
97ad601a05Sjv * you add a constant named "S10_FEATURE_X" to the end of the
98ad601a05Sjv * s10_emulated_features enumeration that represents the backported fix and
99ad601a05Sjv * S10_FEATURE_X evaluates to four, then you should create a file named
100ad601a05Sjv * /usr/lib/brand/solaris10/4 as part of your backport. Additionally, you
101ad601a05Sjv * should retain the aforementioned emulation but modify it so that it's
102ad601a05Sjv * performed only when S10_FEATURE_IS_PRESENT(S10_FEATURE_X) is false. Thus the
103ad601a05Sjv * emulation function should look something like the following:
104ad601a05Sjv *
105ad601a05Sjv * static int
106ad601a05Sjv * my_emul_function(sysret_t *rv, ...)
107ad601a05Sjv * {
108ad601a05Sjv * if (S10_FEATURE_IS_PRESENT(S10_FEATURE_X)) {
109ad601a05Sjv * // Don't emulate
110ad601a05Sjv * return (__systemcall(rv, ...));
111ad601a05Sjv * } else {
112ad601a05Sjv * // Emulate whatever needs to be emulated when the
113ad601a05Sjv * // backport isn't present in the Solaris 10 image.
114ad601a05Sjv * }

1231e71ca95cSGerald Jelinek * In S10 we had the following flag:
1232e71ca95cSGerald Jelinek * #define AUDIT_USER 0x0040
1233e71ca95cSGerald Jelinek * which doesn't exist in Solaris Next where the subsequent flags are shifted
1234e71ca95cSGerald Jelinek * down. For example, in S10 we had:
1235e71ca95cSGerald Jelinek * #define AUDIT_GROUP 0x0080
1236e71ca95cSGerald Jelinek * but on Solaris Next we have:
1237e71ca95cSGerald Jelinek * #define AUDIT_GROUP 0x0040
1238e71ca95cSGerald Jelinek * AUDIT_GROUP has the value AUDIT_USER had in S10 and all of the subsequent
1239e71ca95cSGerald Jelinek * bits are also shifted one place.
1240e71ca95cSGerald Jelinek *
1241e71ca95cSGerald Jelinek * When we're getting or setting the Audit Policy parameters we need to
1242e71ca95cSGerald Jelinek * shift the outgoing or incoming bits into their proper positions. Since
1243e71ca95cSGerald Jelinek * S10_AUDIT_USER was always unused, we always clear that bit on A_GETPOLICY.
1244e71ca95cSGerald Jelinek *
1245e71ca95cSGerald Jelinek * The command we care about, BSM_AUDITCTL, passes the most parameters (3),
1246e71ca95cSGerald Jelinek * so declare this function to take up to 4 args and just pass them on.
1247e71ca95cSGerald Jelinek * The number of parameters for s10_auditsys needs to be equal to the BSM_*
1248e71ca95cSGerald Jelinek * subcommand that has the most parameters, since we want to pass all
1249e71ca95cSGerald Jelinek * parameters through, regardless of which subcommands we interpose on.
1250e71ca95cSGerald Jelinek *
1251e71ca95cSGerald Jelinek * Note that the auditsys system call uses the SYSENT_AP macro wrapper instead
1252e71ca95cSGerald Jelinek * of the more common SYSENT_CI macro. This means the return value is a
1253e71ca95cSGerald Jelinek * SE_64RVAL so the syscall table uses RV_64RVAL.
